Its actually quite good, low-cost steel that performs like midprice steel. 2. I have a few examples below for steels that I have ranges of hardness tested for both toughness and edge retention. Steels with only vanadium carbides have the best balance of properties because the hardness of carbide matters for edge retention but doesnt for toughness. Because of its difficulty in sharpening and machining, its very rarely used and comes with a high price premium. Approximately the same hardness, yes. D2 has a relatively high amount of carbon in its composition (1.55%), more than twice as much as AEB-L (0.68%), but most of that carbon goes into making chromium carbides instead of into solution in the steel matrix, leaving D2 with only ~0.5% C in solution and very large carbides that are good for wear resistance but bad for toughness. This showed that XHP and ZDP-189 have significantly lower corrosion resistance than other stainless steels. All Rights Reserved. I have the average composition of the steels rated above (plus some extras) so you can see what the different names refer to. 0.62% of Carbon: Makes knives harder and more resistant. While 9Cr18MoV steel is highly corrosion resistant due to the addition of Cr, and Mo. But its very cheap, and, when ground appropriately, it can be a real winner from a value standpoint. That provides 14% Chromium and offers excellent corrosion resistance. There are significant differences between them because 14C28N is stainless steel, while D2 steel is a semi-stainless tool steel. Only a few years ago Elmax was pricey, but competition has driven it down to reasonable levels, making it a decent value. Aluminum oxide is used in most common sharpening stones and it is softer than vanadium carbide, which makes sharpening high vanadium steels more difficult. LC200N has similar properties to those two but with saltwater levels of corrosion resistance. Is that regression line (or other trend line?) https://knifesteelnerds.com/2018/12/03/cryogenic-part1/ most knives are being made out of these and other mediocre steels like 14c28n, 420j2, 425m. Austenitizing is the process where the steel is heated to high temperature prior to quenching (rapid cooling) to harden the steel. Sorry, most of my previous comment was borderline word salad. However the 14c28n steel would be great for an EDC knife with typical usage. After the steel is quenched it is reheated to a lower temperature to increase toughness and decrease hardness. 8Cr13MoV is comparable to the Japanese AUS-8 but containing slightly higher carbon content. Edge retention often refers to the ability of a knifes edge to maintain its sharpness during use. This is a virtually stain-proof steel suitable for all sorts of aquatic environments. Alpha Knife Supply sells 26C3 btw. . The solid lockup and decent blade design make these two knives well suited for camping. ApexUltra is a steel that we are working on that had excellent properties in small batch production (50 lbs). 14C28N is a type of high-performance stainless steel used in knife-making. Should you continue to scroll further, you may find yourself lost in a seemingly endless list of knife steel wealth and knowledge. I guess that was before I started reading. This is the steel used in Swiss Army knives and is excellent for beginner sharpeners. The performance of these blades are equally admirable. The steel comes with increased wear and abrasion resistance properties. D2 is carbon steel that has high toughness and durability. rex 121 I always thought VG10 to be way more chippy/less tough compared cpms45vn. at least it has some vanadium over the 420hc. In general, the more carbide the steel has and the larger the carbides the lower is the toughness. However, I would argue that pure material removal is usually not the limiting step for ease in sharpening. Other factors that can be added in are corrosion resistance, hardness, and cost. Its hard enough, tough enough, and stain-resistant enough. Sandvik 14C28N steel offers excellent corrosion resistance, exceptional toughness, good edge retention, and is easier to sharpen. On the spreadsheet, youve grouped AUS-8 and 8Cr13MoV. D2 has been around for more than 20 years, an eternity in. Liquid steel is sprayed through a tiny nozzle, solidifying into a powder. Micarta 14C28N vs. D2. Things are similar with resistance to chipping and edge deformation. 14c28n is the most popular material for the knife: stainless steel and made by the Swedish company. I would like to see the rating and performance on test of the Chinese Steels, that some people use to say its cheap garbage, like 3Cr13MoV, 4Cr13, 4Cr13Mo, 4Cr14MoV, 5Cr15MoV, 6Cr13MoV, 7Cr17MoV, 8Cr13MoV, 9Cr13MoVCo, 9Cr18MoV, 9Cr19MoV, and the 14cr14MovNB to see if they are similar, worse or better than the steels that they copyi believe we gonna have some good unexpected results. It also improves edge retention and strength. I guess the question is whether toughness increases faster than edge retention decreases. However, it falls behind the Bohler steel in corrosion resistance. Honestly, yes, because its perfect steel for your knife, besides it depends on which knife, so when youre talking about chef knives, then 14c28n would be an ideal pick thanks to professional corrosion resistance and edge retention. I think they are complementary and you should watch/read both. Deburring of edges often takes even longer than removing material to produce the edge. The chart below has dotted lines which indicate the average effect of hardness for any given steel. and yet millons of knives are being made out of 1.4116 (aisi 420mov?) I also added a few more steels in this study. It can dull your edge, cause pitting, and damage the structural integrity of your knife. 14c28n vs. AUS-8 Steel There are a lot of different types of steel out there . Is there a reason SG2/R2 are not included in the lineup, despite being one of the most popular ones? By accepting all cookies, you agree to our use of cookies to deliver and maintain our services and site, improve the quality of Reddit, personalize Reddit content and advertising, and measure the effectiveness of advertising. Below, weve listed some of the attributes you might want out of your steel and given some examples in both the more expensive powder metallurgy steels and more affordable conventionally produced steels. AEB-L and 14C28N are the best in the high toughness group. AEB-L and 14C28N also have moderate edge retention though of course much lower than vanadium-alloyed powder metallurgy steels like S30V or M390. You can read more about these factors in my book Knife Engineering. How do its properties compare to other steels? Carbon steels are those that have primarily carbon added to them with some Mn or Si as well. Between the assisted open, weird looking texture designs, and the stainless steel handle, the Cannonball has a lot of features I don't normally like, but even I have to admit it's a good design for the price. You need a hard medium to sharpen it like diamond or boride. This is good for ease in heat treating in large batches and for even cooling that greatly reduces warping and size changes. And easy to sharpen in our experience; and that will get an excellent razor edge that lasts for a reasonable price of time. 14C28N knife will dull faster, but it is easy to sharpen. Its hard to say. Because of its abrasion-eating hardness, knives with REX 121 come at an exceptionally high price. Most of the midrage ifferings have 14c28n, how does it compare to d2 in your experience? This is one of the better steels on the market. Low Carbon steels like AEB-L wont hold up to wood cutting even though it can hit 64 hard, it just doesnt have enough Carbon.. This is an American-made powder steel produced by Crucible and developed specifically for knives with the aid of the knife guru Chris Reeve (maker of the vaunted Sebenza, among other gems). D2 knives offer higher edge retention than 14C28N knives, which is attributed to the high carbon elements and hardness of D2. These steels are typically used by forging bladesmiths, traditional folders, and some production fixed blades. I wont go into detail about those here. Its an update of its 12C27 and 13C26 steels, which were developed for use in shaving razors. Most low alloy tool steels and carbon steels also have fine carbide structures without powder metallurgy processing. Oh, thats great, thanks. While some are into that type of thing, if youre familiar with a specific steel and want to compare it with another, you should definitely click on that button below. AEB-L is rarely found on production knives but can be found on custom knives easily. Many steel ratings articles pay lip service to the importance of heat treatment without providing examples. 14C28N is stainless steel, and its knives offer excellent rust resistance and toughness than D2 steel. In nitrogen steels, nitrogen is used as the iron-hardener instead of carbon, thus limiting the possibility of rusting. You do not expect the prices to be as low as those of low-end knives, but you will get high performance at affordable prices with either. Does that mean that companies like Tops, Kabar and ESEE would be better off using 420HC instead of 1095 on their fixed blades? It also tops out around 60-61 Rc like LC200N and needs relatively careful heat treating to even be that hard. The blackwashed D2 steel blade of the Kershaw Cannonball offers pretty good corrosion resistance for D2. Is this at the same hardness? third and most important is what happened to the burr. 14C28N steel is as a result of a more corrosion resistant version of the 13C26 steel. 420HC doesnt hold an edge well, but its relatively stain-resistant and tough. Thanks! Despite its age, its a truly superior steel. Vancron would work well in a kitchen knife. I see tables that compare Toughness,Edge Retention,Corrosion Resistance. I was the heat treater, but after HT to only 58-59 hardness the blades went to the surface grinders for finishing and I remember them going into the packing boxes with mirror polished edges. Finally, in this 14c28n vs d2, we hope you get the right one. However, high wear resistance means that abrasives are used up more rapidly, more careful grinding is necessary to avoid overheating, finishing and polishing is much more time consuming, etc. If you want for best steel 14c28n and others steel then you can ready 14c28n vs 420hc review. Pretty interesting that regrinding a knife you already have can seemingly take its performance to that of significantly better steels. Nitro V is also significantly cheaper than many other steels with this level of performance. In a pocket knife the total amount of steel is rather small. In its most basic form, steel is just iron and carbon, but people have been studying, experimenting with, and perfecting steel with other elements for specific applications for millennia. Having 1.5% Carbon does that. Become a patron and gain access to awesome rewards including early access to articles or a Knife Steel Nerds mug! Great for tensile strength and Edge retention. This isnt exactly how steel works; different properties are difficult to increase without affecting something else. Now that we know what each factor represents, we can see how the steels rank against one another. I test corrosion resistance of steels by heat treating 1 x 1.5 inch coupons, finishing to about 400 grit, and then spraying with water. D2 steel does not contain enough chromium to make it stainless steel. In fact Id be delighted to have your experience checking my thinking! https://www.patreon.com/Knifesteelnerds, Click to share on Twitter (Opens in new window), Click to share on Facebook (Opens in new window). You showed some pictures in this article of the effect on what we might call "effective toughness" of thinner edge angles vs thicker edges in the same steel at the same hardness. Mostly it has been presented piecemeal with all of the studies that we have done on optimizing heat treatments of different steels like CPM-CruWear, AEB-L, 52100, etc. Choose a factor below to start sorting. What carbon/tool steel would you choose for a survival knife if a PM steel was too expensive? Both knives come at an affordable price for high-end knives. It gets exceptionally sharp, a nod to its origins as a razorblade steel. One argument I see consistently leveled against 8Cr13MoV compared to AUS-8 is that of the consistency of the composition. Theyre excellent for choppers, hard-use folders, and outdoor knives that see impacts and heavy use when used at medium hardness. However,M390, CTS-204P, and CPM-20CV are all pretty difficult to resharpen, so maintain that edge! SG2 Therefore, if your priority is a knife with the best toughness on the market, you can never go wrong with the varieties of 14C28N. Knives are one of our oldest tools, so it makes sense that they have evolved into thousands of styles since the first person chipped one out of stone. I like it in the Seki City Spydercos, but I would like to know what ratings you would give it. Maxamets hardness results in incredible edge retention and a nightmarish sharpening and machining experience. The ratings in this article rate ease of sharpening primarily based on wear resistance, but if a knife is difficult to sharpen, there may be other factors in play. They lack the carbon necessary to hold an edge, even during mild use. Thanks in advance, Simon, For hard use everyday cutting in a packing company, Everything from fome, cardboard, tape, thick plastics, And plastic wrap that is against metal. D2 is another medium-range tool steel. Read more. Several factors arent related to the steel you choose but seriously affect the nature of your knifes performance. You can see micrographs of different knife steels to compare their carbides in this article. D2 is mainly considered decent budget steel that comes with better edge retention than the 14C28N. I cant seem to match steel to the SS data points on the toughness/tcc graph. Generally this is code for difficulty in abrading away steel. Sorry about the misinformation. Its a costly and challenging process, but it makes extremely fine-grained steels, some of the best for knives, and makes some processes that were previously impossible a reality. the problem is in the innumerable combinations of grades, grains sizes and coatings available. Like S90V, its a high-hardness steel, but its more balanced than S90V. There you said 7.6 for 420HC. One of the more common stainless steels, and one readily available in lots of different places worldwide, AUS-8 is a decent all-around steel. It mainly made for knife and it high in Chromium for excellent corrosion resistance. INFI is also quite hard and sharpens easily. Often used for combat knives. However, Kershaw asked Sandvik to make their 13C26 steel more resistant to corrosion, and the result was 14C28N. 14C28N VS Steel. Three main characteristics differentiate steels from one another: corrosion resistance, hardness, and toughness. The unique process used to make LC 200N results in a fine-grain structure. Cookie Notice What it is: D2 is a carbon tool steel with a relatively high chromium content, prompting some to call it a "semi-stainless" steel. Another common heat treating choice that is not even categorized as a mistake is tempering in the high temperature regime (~1000F) rather than the low temperature regime (~400F). See the chart below showing 52100 steel that was overaustenitized (unintentionally) by a knifemaker that sent me specimens for toughness testing. There are also hardness/toughness and hardness/TCC charts.but no tables backing this charts. It improves wear resistance and hardenability. Rowens heat treat on ESEE knives that use 1095 is exceptional; KA-BARs is less so. And a label: AEB-L. I can also say from personal experience that marine grade plywood will chaw up your saw blade and battery a lot quicker than standard plywood, but that probably says more about the glue that was used than the wood. When the blade gets messed up I just replace it. Below shows pictures of a 61 Rc knife that was impacted with a 3/16 rod at different energy levels. Tanto worldwide, even the chinese have an equivalent (8cr13mov). When it debuted, Sal Glesser described XHP as a combination of D2s hardness and 440Cs corrosion resistance. 440B Maxamet is one of two current high-hardness kings, with HRc marks in the high 60s approaching 70, a hardness usually only seen in carbide steels. D2 will go through a lot more rope at 58-59 hard than AEB-L will at 64 hard. Also, what kind of steel is used for utility knives? Hi Larrin Your estimate of 420HCs corrosion resistance is different here than in your October, 2019 post on corrosion resistance testing: https://knifesteelnerds.com/2019/10/14/corrosion-resistance-testing/ 1. If you purchase this types of knife, without any hassle you can easily re-sharpening. VG-10 steel also has the same level of toughness as 14C28N and the same level of corrosion resistance. Thats a pretty large difference in two budget steels that are often compared to each other. 1095 stains easily and thus is often coated, especially in fixed blades. Or even if they try to be more open to importance of toughness, the good reputation of the high edge retention steels means that they get inflated toughness ratings along with it. Tougher than D2, but less wear-resistant. Opinel Number 9 in carbon steel, and a Cold Steel Tanto Lite in their stainless steel. 14c28n steel and D2 steel are both high-quality knife steels. Note just because a blade is made from the premium or high-end steels listed above does not automatically mean its better than the lesser steels. We looked at common steels used by popular knife brands to help you select the right material for your blade. Both of those things are no longer an issue as I now have way too many articles and a book. That is an air-hardening- high carbon, high chromium tool steel. On the other hand, in d2 air-hardness steel, you cant differentially temper the blade-like other high carbon steel because the steel can also be challenging to sharpen. are after the ratings. In many cases, the D2 edge sharpness may last a bit longer. Did you change the estimate based on more testing? Who looking for latest, high carbon, then the Kershaw Natrix Copper Pocketknife. With steels that have a small amount of carbide the size of the carbides can be kept small through processing (see the AEB-L micrograph earlier in the article). 14C28N is a stainless steel that was developed specifically for use in knives. And steels with at least 10% chromium are probably stainless, except for several important exceptions like D2 and ZDP-189. These two knives are a little bit more than a pretty face. Steels 7Cr and below arent worth your time or money. But a few overly vocal forgers were making claims about it that clearly were not true especially when comparing it to 5160. 14C28N and D2 steel are not the same. Also D2 is not stainless as at least 5% of its chromium is tied up in carbides where it doesnt help prevent corrosion. The ESEE had significant edge damage while the MagnaCut knife did not. Thanks! In particular, I have found the ESEE/Rowen 1095 to be less likely to chip and better at holding an edge than the KA-BAR version even in knives with the same role, thickness, and blade length. This is a nitrogen steel that is extremely corrosion-resistant so much so that its used in knives designed to go in salt water, among the most difficult conditions knives are used in. And while youll find it mostly in expensive knives, quite a few approachable M390 blades exist. Continue with Recommended Cookies. High Alloy Tool Steel and High Speed Steel Ratings. Though the volume of carbonitrides in the steel is relatively high. I was recommended the Rat 1 in D2 and I also found that I really like the design of the Ruike p135 and p128. Its possible that there are steel manufacturers with better processing which would lead to an even carbide distribution but I cant say that without seeing it for myself. Its in the same class as Vanadis 8 and 10V. Spyderco is the only production company using this steel, though Michael Gavik of Gavko knives produced a number of customs in LC 200N. 440C steel The consent submitted will only be used for data processing originating from this website. I like it. Are you looking for 14c28n steel with other steel? In fact, its not technically a steel at all, as it uses titanium and nickel. It mainly made for knife and it high in Chromium for excellent corrosion resistance. Since the heat treatment is done before you get your knife, and its impossible to tell how good the heat treatment is with your eye, you often must rely on the manufacturers reputation for a good heat treat. They are usually chosen for their looks rather than performance. Here, youll learn the different factors that go into each steel, ratings for a wide variety of steel alloys, and youll get some recommendations for types of knives different types of steel work well for. It is most useful for steels with large amounts of carbide but also helps to be able to add certain carbide types. However, to choose the best knife for you must consider all the properties, including toughness, edge retention, corrosion resistance, and ease of sharpening. Let the job at hand be your guide. They make excellent everyday carry steels, especially for light- and medium-duty tasks. Marco, BSc Chem. The greatest living knifemaker and one of the greatest knifemakers of all time, Michael Walker, calls AEB-L one of his favorite steels. Rather than upgrade from D2 to M4 or S30V just drop the angle from 40 degrees to 30 degrees. Powder metallurgy steels with low vanadium content like CPM-1V and Z-Tuff/CD#1 have extremely high toughness. D2 is a high carbon, high chromium die steel and is the highest carbon alloy tool and die steel typically used in knife making. Steels do come at various price points, however, depending on the cost of producing them and the cost for the knife company to work with them. Sign up to receive GearJunkie content direct to your inbox. This makes for a great slicing knife and a perfect steel, in my opinion, for a regular-use, everyday-carry folder. The steel loses some of the chromium in solution for corrosion resistance to form these fine carbides for hardness. My name is Jonathan M, and Im a passionate Mechanical Engineer, a knife enthusiast, and the author of this website. For these reasons D2 steel is a good for smaller folding knives, but is not ideal for large fixed blades such as dedicated choppers and large survival knives. There are still a few things I dont know but we have enough information to make educated guesses where data isnt available. We did the research to help you find the best hunting knife for your needs and budget. For example, below is a video comparing a 1095 ESEE knife at 55-57 Rc and a MagnaCut knife at 62.5 Rc, both with the same edge angle. and why would anyone want to use it when 420HC looks so much better for a simple stainless steel option. Very obtuse edges resist chipping better but dont hold their edge as long and dont cut as well. Any thoughts how Sleipner might fare in the ratings? I have a question about the chart Question. : knife a with a toughness of 5 and an angle of 20 degrees will perform as well in edge retention as knife b with a toughness of 3 and an angle of 15 degrees. D2 steel is more durable than 14C28N, but it scores lower in terms of ease of sharpening and corrosion resistance. It was your original article on ratings that brought me to knifesteel nerds so its great to see your results put back into a form that will no doubt be distributed \ plagiarized widely, hopefully leading to more rational thought and better understanding by the knife consuming public (not that the misleading marketing will go away). Its a very hard steel and is exceptionally difficult to sharpen. The studies confirmed that the primary controlling factors are hardness of the steel, volume of carbides, and hardness of the carbides. I made most of my leather knives from O1v (O1 with .20V) that I hold at 1475 for 15 mins and quench in 120-130 F AAA oil and Kevin Cashen is where those parameters came from btw. Crucible intends SPY27 to be good all-around knife steel. In other words, Rex 121 would be the most difficult to sharpen and 5160 and 8670 would be the easiest. : at a given toughness, magncut will have better edge retention in real life applications than s90v if it has optimal geometry (or maybe it wouldnt, just an example). Therefore powder metallurgy is not necessary for certain steels, or could even be slightly detrimental. and yet millons of knives are being made out of 1.4116 (aisi 420mov?) The edge retention and ease of sharpening have been what we expect with D2. Note that corrosion is detrimental for the cutting edge. The line is only in the neighborhood of 5 of the datapoints. That is professionaly popular such as the Japanese designation SKD11, Uddeholm Sverker 21, German designation 1.2379, Hitachi SLD and others. Its so high in hardness that Maxamet knives usually ship with desiccating packages. Stainless steels usually top out around 64 Rc and may require careful heat treating to get there. Even it enhances corrosion resistance and wear resistance. If you're stuck between 14C28N and 440C, here's a breakdown of the pros and cons of each type of steel. 12C27 Thanks to its very high hardness (64-66 HRc compared to the average of 58-62 HRc), ZDP-189 can be ground thinner and sharpened less often. The bump in hardness comes from precipitation of fine carbides in the steel, which include chromium carbides. As from features, for presenting d2 continue to grow in the knife industry, generally because of their working performance and reasonable price, a lot of superior low budget knives are building their reputation. CPM 4V If you want to learn more than keep reading past the ratings. It can build a knife that sustains a sharp cutting edge for long periods and is sufficiently wear-resistant. Another is that 8Cr13MoV is a generic name for a specific composition while AUS-8 is a name of a product by a specific company. Uddeholm lists it as somewhat worse in toughness than A2 but somewhat better in wear resistance. This is a major tradeoff between improved cutting ability and edge retention with an acute angle vs a strong and chip resistant edge with an obtuse angle. This does not predict which knife will cut longer or be more resistant to chipping. You will get an ultra-sharp edge with 14C28N knives. AR-RPM9 I hope you will find value in the articles on this website. The claim is that they align the blades edge, pushing any slightly rolled over bits back into place and thus preserving the cutting ability of the knife for longer. grivory Its OK to be a steel snob, but keep in mind that you dont have to if you want a good knife. And Ive done a lot of experimental work on knife steels where I feel more confident in my own ratings. In this article, we will discuss the characteristics, pros, cons, and differences between 14C28N and D2 knives to help to make the right choice. second it might be of importance which way you sharpened because if against the edge the steels might have reacted differently to the contamination remaining on the edge.
