But among the steels youll find at Cabelas and the like, this is a pretty good choice. A more obtuse edge angle is much more resistant to chipping than an acute edge. 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. In nitrogen steels, nitrogen is used as the iron-hardener instead of carbon, thus limiting the possibility of rusting. It shows 3 stainless steels from 750-800tcc but the edge retention graph only has 1 SS in that range, S90v. INFI is also quite hard and sharpens easily. What carbon/tool steel would you choose for a survival knife if a PM steel was too expensive? The big names in powder metallurgy are Crucible (CPM- steels), Carpenter (CTS- steels), Bohler Microclean (M390), and Uddeholm Superclean (Elmax, Vanax). Low Alloy tool steels have small alloy additions to increase hardenability so they harden more easily in oil rather than water. 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. I would love to see a Tungsten-Carbide blade (like Sandrin is using) and how it compares for Edge Retention, Toughness and Corrosion Resistance especially how it compares to s90v. 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. In general, steels look worse as you go up in hardness because the toughness is reduced by more than the edge retention is increased. Marco, BSc Chem. However, it falls behind the Bohler steel in corrosion resistance. Below shows charts summarizing tests of different steels for the major categories discussed so far, low alloy steels, high alloy non-stainless steels, and stainless steels. Non-stainless steels can be heat treated to 66 Rc or even higher depending on the particular steel. Or, is this perhaps a historically useful practice that made sense on softer/less tough steels, but would make less sense on some newer steels that can be used at higher hardness and thus higher edge stability? This makes it a great choice if you don't have . at least it has some vanadium over the 420hc. 2) you do not go into the sharpening in much detail. If youre looking for all all-around best knife steel, youd be hard-pressed to find one better than Bohler Uddeholm M390. AEB-L and 14C28N are the best in the high toughness group. A Japanese powder steel, ZDP-189 is essentially the polar opposite of 3V its uber-hard instead of uber-tough. Also known as Z-Finit, Zapp produces this steel in America. Poor heat treatment can make a knife too hard, too soft, hard to sharpen, easy to deform, or cause other issues. And Michael Fitzgerald, Tim Marais, and Head VI for increasing their contributions. AEB-L is rarely found on production knives but can be found on custom knives easily. 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. What would you rate the toughness of CPM-D2. And Mn and Si isnt shown at all for the high alloy steels, even though those elements are added to all of them. and yet millons of knives are being made out of 1.4116 (aisi 420mov?) rust resistance.Best of all most knives made from this steel can be had for well under $75.In my opinion Sandvik 14c28n is a better overall steel than that of Aus8,420hc,or ANY of the . 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. This means consumers should be able to maintain these quality knives at home. Around 61 Rc usually. https://knifesteelnerds.com/2018/12/10/cryogenic-processing-of-steel-part-2/ And steels with at least 10% chromium are probably stainless, except for several important exceptions like D2 and ZDP-189. Did you change the estimate based on more testing? I was thinking maybe Sleipner or A2 would be best if a PM steel was out. Read more. Its very similar chemically to RWL 34 and ATS-34. It boasts an incredible ability to continue cutting long after it seems dull. And its not made of steel. I see very little about cryo outside of journal articles, and I wonder which knifemakers use it. It also tops out around 60-61 Rc like LC200N and needs relatively careful heat treating to even be that hard. My favorites of the high edge retention group are Vanadis 8 and CPM-10V. I was struggling to simplify all the Rockwell/Youngs Modulus stuff for readers when I came across your site. It is an upgrade of 12C27, and 13C26 steel initially used to make blades for shaving razors. Knifemakers use dozens of steel types to create knife blades. This steel is quite corrosion resistant and sharpens easily. Because of the material difference, the blades differ in toughness, edge retention, corrosion resistance, and ease of sharpening. and our Being stainless is not an on or off property, and some stainless steels are more resistant to corrosion than others. SPY27 Stainless steels usually top out around 64 Rc and may require careful heat treating to get there. 14C28N is offered on midprice knives and is one of the better steels on a dollar-for-dollar basis. Both knives were chopped through a nail. Find your right answers here! 14c28n is the most popular material for the knife: stainless steel and made by the Swedish company. LC200N Lots of information is still specific to this article, however. Read about my tests in this article. Is Vancron SuperClean a good choice for a chef knife? We can predict edge retention of a steel within a relatively narrow band based on hardness and carbide volume. CPM 154 The steel loses some of the chromium in solution for corrosion resistance to form these fine carbides for hardness. Corrosion is not only cosmetic. Steel with high wear resistance is more costly to manufacture, as the knife company goes through more abrasives to grind the knives. Most of these steels rely on particle metallurgy and are therefore more expensive. The most significant cost increase comes from powder metallurgy, used to create most of the expensive knife steels. 14C28N is the highest-selling steel of Sandvik, a Swedish steel company. Where the black-finished 1.4116 version has a simple, full flat grind, the D2 version has a compound flat grind that ends halfway up the blade's height. there seems to be an optimal procedure for every alloy (provided its heat treated to industial standards). 14C28N vs. D2. D2 knives offer higher edge retention than 14C28N knives, which is attributed to the high carbon elements and hardness of D2. In general, higher carbon steels have higher edge retention but lower toughness. It has excellent edge retention, corrosion resistance, and ease of sharpening. Below shows Vanax tempered at 400F on the left and 1000F on the right after 1% saltwater for 24 hours: There are many other ways in which knife steel performance can be reduced through heat treatment but I cant cover them all in this article so hopefully these illustrative examples will be enough. 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. A mirror finish is the best at resisting corrosion and a rough finish means rust and corrosion is more likely. The ESEE had significant edge damage while the MagnaCut knife did not. AEB-L is a non-powder steel produced by Swedish steelmaker Uddeholm. 14C28N steel is the improved version of 13C26 with better rust resistance. 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. are after the ratings. Does that mean that companies like Tops, Kabar and ESEE would be better off using 420HC instead of 1095 on their fixed blades? Tough steel can handle impacts without gross chipping or a tip breaking off. So hard vanadium carbides means you get more edge retention for a given amount of carbide. Not every wood is soft pine. D2 is mainly considered decent budget steel that comes with better edge retention than the 14C28N. I have a few examples below for steels that I have ranges of hardness tested for both toughness and edge retention. The Sandvik 14c28n steel is ideal for the manufacturing of steel knife blades. I see tables that compare Toughness,Edge Retention,Corrosion Resistance. third and most important is what happened to the burr. Therefore you will use it for a long time without requiring frequent sharpening. However, the 14c28n provides perfect edge retention with a maximum hardness of 62Hrc and the mixture of Chromium and Carbon. This is about comparing steels to each other rather than a limitation of an individual steel. Ease of Sharpening: One advantage of 8Cr13MoV is that it is easier to sharpen than D2 steel. If you purchase this types of knife, without any hassle you can easily re-sharpening. I couldnt find much on 5160 steel and from a knife makers point of view if you are saying youre the preferred supplier of special ops than I dont understand this choice in knife steel. It has high levels of chromium and carbon, making it extremely resistant to corrosion. Must-Have Bowie Knives for Your Collection, What is Micarta and What Makes It a Great Knife Handle, Top 8 Reasons Why Knives Make the Best Gifts, Pocket Clips: Carry Safely and Comfortably, Make a Knife Your Own with Accessories & Customization. It does have chromium but is not as sufficient as required to be a type of stainless steel. Diamond and CBN stones make sharpening those steels easier. Toughness is a measure of how much resistance a steel has to fracturing. Note:There is a powder-metal version called CPM154 thats purer than the non-powder version, making it easier for knifemakers to grind. s30v I guess the question is whether toughness increases faster than edge retention decreases. These steels favor edge retention over all else. This is especially important for chopping knives and for knives with thin edges for enhanced cutting ability and edge retention. The blackwashed D2 steel blade of the Kershaw Cannonball offers pretty good corrosion resistance for D2. 14C28N knives offer better toughness than D2 knives. The high hardness makes it all but impossible to sharpen and machine. This is an old high-carbon (non-stainless) steel. Wusthof Classic Ikon 8-Inch Cooks Knife Review, Victorinox Fibrox Straight Edge Chefs Knife Review, What is Cts bd1 steel? 14C28N steel is known to offer among the best if not the best toughness in knife steels out there. Hi Jimmie, thanks for your comments. D2 steel Both steels are popular among knife manufacturers and both have their strengths and weaknesses. H1 and 420 also have excellent corrosion resistance but are limited to lower hardness and edge retention. Which knife for best? D2 steel offers better edge retention and wear resistance than 14C28N. Required fields are marked *. M390 I was guessing 5.5 based on your rating of CPM-154. . Anyway, astute comment, but edge retention does mean a lot in woodworking. How long sharpen? One is certainly anti-China bias, as you pointed out. Would be great if some manufactures changed their steels based on this information. If the steel is overheated in austenitizing, very large reductions in toughness are possible. Sharpening the knives might be challenging, but the D2 knife is high quality and affordable. Yes its very easy to sharpen but it doesnt hold an edge at all. There has been some internet controversy over the grinding and heat treat of this steel. The reason is because sharpening and edge geometry will also greatly control properties. Is that accurate? You can read more about these factors in my book Knife Engineering. This is one of the better steels on the market. They differ little in composition and treatment. Its hard enough, tough enough, and stain-resistant enough. Spyderco is the only production company using this steel, though Michael Gavik of Gavko knives produced a number of customs in LC 200N. I also have meat cleaver 1,4116 ,58RC that I order and was looking up if its a good steel or did waist money and need to return it. Jesse Jarosz, a custom maker from Montana, regularly uses AEB-L. If you want to learn more about a specific steel, you can click it in the sorted listings below. 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. CPM-S90V, CPM-S110V, CPM-10V, and Bohler K390 each fit in this category. 14C28N is a stainless steel that was developed specifically for use in knives. This is a non-powder Japanese steel used primarily in Spyderco knives. This is a midprice steel with matching performance. It had better than expected corrosion resistance due to the lack of chromium carbides, a behavior also seen in MagnaCut. Old time 8670, 5160 (known to ignoramuses as 51shitty) and 52100 are excellent choices and arguably better choices than 80crv2. 14C28N steel, also known as Sandvik 14C28N, is stainless steel made by Sandvik, a European steel company in Sweden. Ruike Sandvik 14c28n vs D2 looking at getting a nice larger flipper for a little under 100 AUD. G10 Alloying elements are an important ingredient vital in getting the best steel for the job. Have you tested K390 sufficiently to be able to rate it? Chris Reeves version, which is about two points less hard than others, is quite good. Tougher than D2, but less wear-resistant. It will take you more time and energy to get a sharp edge, but your efforts will pay off because the blades hold the edge longer. Anybody know how the Sandvik stacks up against all these other steels. Thanks. Alpha Knife Supply sells 26C3 btw. https://knifesteelnerds.com/2018/12/03/cryogenic-part1/ Theyre excellent for choppers, hard-use folders, and outdoor knives that see impacts and heavy use when used at medium hardness. What would be the best deal to use I currently alternate between 20CV S35vn and D2. I personally don`t care about stainless (sic! But a few overly vocal forgers were making claims about it that clearly were not true especially when comparing it to 5160. 9cr18mov vs 14c28n. If the knife youre looking at has a 154CM blade, youre fine. Looks like there is no reason to us it over 420HC. In many cases the cost of working with the steel for the knife companies is more significant than the cost of the steel itself. But if when youre searching for tough steel for your outdoor experience camping, or hunting, it would be perfect steel but not the best choice therere other steels with better than toughness that would suit your usage. Plus the charts get messier, and I dont always have data for a wide range of hardness values. I was just comparing AEB-L and 14c28n to decide which steel to get for my next knife project and although 14c28n seems to be a bit more abrasion resistant, my primary goal is toughness and edge stability. Note that corrosion is detrimental for the cutting edge. The biggest change that is seen with powder metallurgy in measured properties is in regards to toughness. 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. Rather than upgrade from D2 to M4 or S30V just drop the angle from 40 degrees to 30 degrees. Its very tough and exceptionally corrosion-resistant. Sandvik 14C28N steel offers excellent corrosion resistance, exceptional toughness, good edge retention, and is easier to sharpen. 14C28N steel is as a result of a more corrosion resistant version of the 13C26 steel. does 1.4116 deserve the title of title of ultimate trash steel? It mainly made for knife and it high in Chromium for excellent corrosion resistance. However, Kershaw asked Sandvik to make their 13C26 steel more resistant to corrosion, and the result was 14C28N. 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. So what is the best steel for knives? I hope you will find value in the articles on this website. D2. At the end of the article I gave a list of reasons why I hadnt made my own ratings chart, two big reasons were: 1) I didnt yet have articles explaining what edge retention and toughness even is (this was early on in Knife Steel Nerds), 2) I didnt have good experimental numbers on many steels. I know that one does not normally make knife blades of titanium, but I gather that Ti is extremely corrosion resistant, used for saltwater applications, etc. I have the average composition of the steels rated above (plus some extras) so you can see what the different names refer to. Each of these contributes to a knifes overall performance. And a label: AEB-L. Its a good balance between all three attributes, being relatively hard, tough, and corrosion-resistant. 14C28N steel is not very hard steel which makes it easier to sharpen. But I think it would have much higher toughness than any of the steels on the chart. I havent tested Sleipner yet. These images are taken from my book Knife Engineering. Not as tough as the best carbon steels, it's tougher than most . The majority of knives target 63 Rc or below so this limitation of stainless steels does not always come into play but can be an important factor for certain knives targeting high performance and thin edges. False treatment and geometry upheld by Made in USA is like buying 8Cr from China (except late A.G) My personal experience tops with Vanadis 4E, CPM-M4, RWL-34 and the likes. And while it can be hard depending on the heat treat, I have found it easily chips, causing microscopic dings in the edge when hardened to a high level on a thin blade. However,M390, CTS-204P, and CPM-20CV are all pretty difficult to resharpen, so maintain that edge! 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. It can build a knife that sustains a sharp cutting edge for long periods and is sufficiently wear-resistant. Diving into the pool of knife personalization possibilities is a fantastic way to fend off the post-knife-buy blues. Sandvik later came out with 14C28N which is a slightly improved version of 13C26. Its an anomaly in the knife world and quite puzzling to use. Even though it has very high hardness, its also still decently resistant to corrosion and quite tough. But it doesnt have great wear resistance and thus doesnt hold an edge particularly well. What it is: D2 is a carbon tool steel with a relatively high chromium content, prompting some to call it a "semi-stainless" steel. 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. 1095. I would think that the label applies to either the line or the outlier, but probably not both unless the outlier is a measurement error. Keeping in mind that I have a well rounded Set of sharpening skills. 420 Simple, non-stainless steels of medium carbon content like 5160 also boast high toughness. Rex 45 The sharpening makes the knives easy to maintain because they dull faster and require frequent sharpening. The critical difference between these two sheets of steel is their corrosion resistance. Im not hating on 80crv2 , Ive used it. Stainless steels are more resistant to corrosion but remember that stainless steels stain less, and most of them will still rust in the right conditions. But which? There are significant differences between them because 14C28N is stainless steel, while D2 steel is a semi-stainless tool steel. AEB-L and 14C28N are the best in the high toughness group. 14c28n is the most popular material for the knife: stainless steel and made by the Swedish company. Corrosion on knife steels most usually takes the form of rust, patina, and staining. D2 knives, on the other hand, are challenging to sharpen. Most edge retention tests isolate wear resistance or how long it takes abrasives to dull your edge in whatever youre cutting. Vanax gives up some toughness and hardness vs MagnaCut for saltwater levels of corrosion resistance. Larrin, thank you for this. Conventionally produced steels include AEB-L, A2, 52100, 12C27, 14C28N, and AUS-8/,8Cr13MoV. HA! Anyway, buff up the O1v and it cuts leather easily. Three main characteristics differentiate steels from one another: corrosion resistance, hardness, and toughness. my understanding is that wood is not a particularly abrasive material and a plane is more of a push cut action than a slicing action so I would have though edge stability and sharpness is more important than edge retention meaning ABE-L should work pretty well. 14C28N is stainless steel, and its knives offer excellent rust resistance and toughness than D2 steel. This is a powder steel produced by American steel company Carpenter. But in use, Ive found nothing that withstands the abuse that 3V can take. D2 is a tool steel used in industrial settings. One important concept I want to hammer home is that there isnt one property that is most important. The biggest factor for cost of knife steel is whether it is produced with conventional ingot technology or powder metallurgy. 440B . This is the basis on which I do the ratings rather than a linear scale. D2 steel is more durable than 14C28N, but it scores lower in terms of ease of sharpening and corrosion resistance. Spyderco has produced several production knives with Maxamet, and the steel debuted on the ZT0888. looking at getting a nice larger flipper for a little under 100 AUD. 14C28N knives are easier to sharpen than D2 knives. CTS-204P and CPM-20CV are nearly identical steels made by other manufacturers. I also have a video that summarizes some of the information below while also showing how some of the experiments work. Get for a complete guide about other steel; you can read 14c28n vs 8cr13mov reviews. 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. 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. S90V By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. Is it similar but worse or better at one of the 3 things? Sure if you dont want stainless steel fine, but there are plenty other carbon steels out there much better than 5160. For example, the Si space is blank for several of the carbon steels because they have a relatively wide acceptable range, not because the element isnt added. Edge retention often refers to the ability of a knifes edge to maintain its sharpness during use. That is an air-hardening- high carbon, high chromium tool steel. Elmax In some previous articles I have shown the balance between my toughness and edge retention measurements such as in the following chart, where the high alloy non-stainless are in orange and the blue are stainless: However, one issue with these charts are that difference in toughness is that a linear scale for toughness is a bit misleading for visualizing practical toughness differences. 1) the cvn number is just that, a number. In fact Id be delighted to have your experience checking my thinking! its like with cars, most of them are not a corvette or a porsche. The greatest living knifemaker and one of the greatest knifemakers of all time, Michael Walker, calls AEB-L one of his favorite steels. https://i0.wp.com/knifesteelnerds.com/wp-content/uploads/2021/10/stainless-toughness-10-19-21.jpg?w=757&ssl=1 Furthermore, because of its ultrahigh hardness, Maxamet is very prone to corrosion, probably worse than 1095. High wear resistance is not particularly necessary when only performing chopping, and its good ease in sharpening helps when having to restore the edges. Steels high in toughness are excellent for knives likely to see hard impacts, like large chopping knives. Toughness 3, Edge Ret 8, Cor Res 4? The pictures below show the microstructures of the three classes of stainless steel on the market. The best knife for you should meet your needs and fit your budget. Spyderco has their own salt spray test setup to determine the corrosion resistance and they determined that MagnaCut is sufficiently corrosion resistant for their salt series of knives. im led to believe tha the melting procedure is more important with these steels than the exact composition. Vanadium carbides are among the hardest that form in steel, and chromium carbides are in between iron carbide and vanadium carbide. He is the mind and writer behind Knife Steel Nerds, the go-to source for all knowledge about knife steel. The choice between the two depends on your knife needs. Here its 8. With toughness it is a bit harder to link to only one article as I dont really have a summary of all of the toughness testing that we have done. I have a question about the chart worldwide, even the chinese have an equivalent (8cr13mov). The hardness level of steel is determined using a universal scale called the "Rockwell C Test", commonly called the Rockwell hardness scale (HRC). For this perfect size that for most tasks and the slim tip allows the knife to excel at piercing and detail work. So for most steels they are given a rating at around 59-62 Rc, apart from a few steels that are never used at that hardness. The maximum edge retention available in this group is not particularly high because most of the wear resistance comes from iron carbide, also called cementite, which is the softest of the different carbide types.
