The solid lockup and decent blade design make these two knives well suited for camping. Its not a particularly great cutter, being poor at retaining an edge. It is among the steel knives with exceptional toughness while maintaining excellent corrosion resistance. great work, larrin. Have you tested K390 sufficiently to be able to rate it? In particular, I really care about the toughness / hardness part. Divers, sailors, and anglers need knives that will resist corrosion above all else. Alpha Knife Supply sells 26C3 btw. For this perfect size that for most tasks and the slim tip allows the knife to excel at piercing and detail work. My favorites of the high edge retention group are Vanadis 8 and CPM-10V. Oftentimes steels that are reported to be difficult to sharpen are in fact improperly heat treated and challenging to deburr. Maxamet and Rex 121 are so extreme in terms of wear resistance and edge retention that I rated them higher than 10 because otherwise it throws off the ratings for everything else. . We and our partners use data for Personalised ads and content, ad and content measurement, audience insights and product development. I wont go into detail about those here. Would be great if some manufactures changed their steels based on this information. Its exceedingly tough and relatively hard, but its not stainless. whats even more disturbing is that cvn and fracture toughness sometimes (often?) Is Vancron SuperClean a good choice for a chef knife? Properties: 14C28N: D2: Edge retention: 4/10: 7/10: Ease of sharpening: 6/10: 3/10: Corrosion resistance: 4/10: 4/10: Toughness: 6/10: 6/10: CIVIVI Knives Elementum Folding Pocket Knife 2.96" D2 Satin Blade . Due to its higher Chromium content, S30v is a lot less likely to corrode/rust than the D2 Steel. Tougher than D2, but less wear-resistant. The best scenario is when the steel, heat treatment, and geometry are selected for the knife and the use. That comes with an excellent return of experience that makes it ideal for the manufacturer of outdoor and tactical knife blades. 14c28n is the most popular material for the knife: stainless steel and made by the Swedish company. You can read more about these factors in my book Knife Engineering. What about K390? I mean the box cutter type, with the replaceable trapezoidal blades. Now that is power planer blades, but the principle stands, less carbon and alloy isnt the best for wood working and Id use a steel like 26C3 (1.25% C .30%Cr) for my hand tools and temper them to around 62 hard and use the best angle for wood shaving, not the best angle for cutting rope. and yet millons of knives are being made out of 1.4116 (aisi 420mov?) . That is professionaly popular such as the Japanese designation SKD11, Uddeholm Sverker 21, German designation 1.2379, Hitachi SLD and others. Very acute edges are more brittle but remain sharp for longer and cut very well. The Kershaw Leek is a most popular EDC knife that design by legendary custom knife maker Ken Onion. No mainstream companies use SM100, and the niche makers that do usually charge more than $1,000 for knives with SM100 blades. While not a powder steel, 154CM is widely used in nicer knives. just recently the idea occured tome to sharpen a planer blade like a knife and check out how it performs. And steels with at least 10% chromium are probably stainless, except for several important exceptions like D2 and ZDP-189. Ive found S35VN less chippy even at the same hardness. The 8Cr13MoV vs D2 debate. Are you okay with that? CPM 4V S45VN 440A has more chromium in solution along with a small addition of Mo, but has significant amounts of carbide so the two are an interesting comparison. 14C28N is the highest-selling steel of Sandvik, a Swedish steel company. A more obtuse edge angle is much more resistant to chipping than an acute edge. 1. Edge retention is the ability of a knife to maintain cutting ability during cutting. Heat treatment refers to the heating and cooling steps employed to achieve your knifes proper balance of attributes. I have a bachelor's degree in Mechanical engineering with a specialization in material science. I also have a video that summarizes some of the information below while also showing how some of the experiments work. In other words, heat treating a steel to its maximum hardness does not necessarily mean reduced corrosion resistance. While 14C28N and D2 are both pretty to look at, buyers always regard one over the other. Poor heat treatment can make a knife too hard, too soft, hard to sharpen, easy to deform, or cause other issues. Corrosion on knife steels most usually takes the form of rust, patina, and staining. In many cases the cost of working with the steel for the knife companies is more significant than the cost of the steel itself. We should be suspicious of anyone who is claiming very high edge retention with a steel at low hardness and a small amount of carbide. This means consumers should be able to maintain these quality knives at home. Hammering through hickory, digging at roots in sandy soil, and cutting around bone did nothing to chip, dent, or roll the edge of my 3V knives. 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. However, the 14c28n provides perfect edge retention with a maximum hardness of 62Hrc and the mixture of Chromium and Carbon. in relation to hardness). PESR would be an interesting topic too (also tied to LC200N). The stainless steel rating. 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. With a high level ofedge retention, corrosion resistance, and toughness, it does most everything quite well. Thanks! The excellent corrosion resistance properties of 14C28N are attributed to the high amounts of chromium in its composition. Top quality steel yields perfect toughness, edge retention, wear and corrosion resistance, an easy to sharpen, long lasting and durable everyday carry that will fast become a user favorite. This was not necessarily because of superior toughness but because of the superior strength of the MagnaCut from higher hardness. quite possibly the best steel youll find on a sub-$30 production knife. Read about my tests in this article. This showed that XHP and ZDP-189 have significantly lower corrosion resistance than other stainless steels. Anthony Sculimbrene authors the blog EverydayCommentary.com. Diving into the pool of knife personalization possibilities is a fantastic way to fend off the post-knife-buy blues. 14C28N VS D2 The two sheets of steel are comparable in terms of toughness and corrosion resistance. They make excellent everyday carry steels, especially for light- and medium-duty tasks. 1. vanax 14c28n has less carbon and chromium as compared to 9Cr steel. 2) you do not go into the sharpening in much detail. D2 steel, on the other hand, is tool steel, and its knives shine on edge retention and wear resistance. This is good for ease in heat treating in large batches and for even cooling that greatly reduces warping and size changes. 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. An example of data being processed may be a unique identifier stored in a cookie. It has high levels of chromium and carbon, making it extremely resistant to corrosion. A good quality knife must have sharpness, great edge retention, and a sturdy handle. (Some crazy folks clean their Swiss Army knivesin adishwasher. 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. For high wear resistance and edge retention you want a large amount of hard carbides. If you want to learn more than keep reading past the ratings. 14C28N vs. D2. 14c28n steel and D2 steel are both high-quality knife steels. D2 is another medium-range tool steel. Crucible intends SPY27 to be good all-around knife steel. Its very tough and exceptionally corrosion-resistant. So youre right that a D2 blade will cut more CATRA cards than an AEB-L blade *when theyre both sharpened to the same angle* but AEB-L has much better toughness and can therefore handle being sharpened to a more acute angle without chipping, and a more acute angle is more important to continuing cutting ability than wear resistance is. Read more about how it works here. 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. D2 steel is more durable than 14C28N, but it scores lower in terms of ease of sharpening and corrosion resistance.

Would love to see where S7 sits on the Corrosion/Edge/Toughness meter. https://knifesteelnerds.com/2018/12/17/cryogenic-processing-of-steel-part-3/. For instance, if a 35 edge in 1095 steel at 58 Rc provides appropriate toughness for planing hardwood, what edge angle in, say, AEB-L at 62 Rc might give us a comparable effective toughness? Even it enhances corrosion resistance and wear resistance. However, it falls behind the Bohler steel in corrosion resistance. https://cedric-ada-store.creator-spring.com/listing/brickard-heritage-collectionGood gravy its bricky on thingsSubscribe and hit the bell! thanks thats interesting. Conventionally produced steels include AEB-L, A2, 52100, 12C27, 14C28N, and AUS-8/,8Cr13MoV. Spyderco announced Native 5 Salt with magnacut, but I saw test of magnacut with salt water and it grows corrosionso Salt with magnacut could be a flop. It does have chromium but is not as sufficient as required to be a type of stainless steel. 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. Only a few years ago Elmax was pricey, but competition has driven it down to reasonable levels, making it a decent value. Below shows pictures of a 61 Rc knife that was impacted with a 3/16 rod at different energy levels. The knives can be used in humid and wet environments without rusting. 14C28N knives are easier to sharpen than D2 knives. Great for tensile strength and Edge retention. The material increase machinability and strength. nevertheles its importand to keep in mind what exactly is going on there (abrasive plastic media, loss of most of cutting ability during the first few strokes etc.). It isnt impossible, but contrast may not be very good and the austenitizing temperatures of the two steels arent very compatible. Steels high in toughness are excellent for knives likely to see hard impacts, like large chopping knives. ApexUltra is a steel that we are working on that had excellent properties in small batch production (50 lbs). So, it is quite harder than most other steel variants and retains its edge sharp for a long period. However, many kinds of wood are REALLY tough and very hard on blades. Vancron has a very fine microstructure so it would be tough to beat. You can read about my CATRA edge retention testing in this article. How would n680 compare to m690? 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). On the other hand small but mighty, the pocket knife provides both in professional performance and in arresting good looks. These properties make steel a good choice for making kitchen, fishing, and everyday knives. While higher hardness does lead to improved edge retention the bigger reason to have higher hardness is for resisting edge deformation. Looks like there is no reason to us it over 420HC. Five years ago, S30V had a premium price. Its found on a large number of traditional-style folders. Anyway, astute comment, but edge retention does mean a lot in woodworking. I guess that was before I started reading. 14C28N knives offer excellent corrosion resistance and toughness. There are a few other complicating factors such as carbon in solution and plate martensite, especially in low alloy steels such as described in this article. 14C28N 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. Did you change the estimate based on more testing? In fact Id be delighted to have your experience checking my thinking! There are a few aspects to your question, I think. Nitro V vs 14C28N Last but not least, 14C28N contains comparatively more vanadium elements which makes the carbides more harder and strong, which gives 14C28N a better edge retention. Thank you for such a great article! By that I dont mean that a better heat treatment is not possible, but that major mistakes in heat treating are avoided. S90V Toughness 3, Edge Ret 8, Cor Res 4? Read more. It confirms what I always suspected and what anyone could have figured out by reading the technical data. I like it. After the steel is quenched it is reheated to a lower temperature to increase toughness and decrease hardness. AEB-L 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. Though technically not a stainless steel at least 14% chromium, and D2 usually has 12% its relatively corrosion-resistant. The both blade are equally wear resistant. We and our partners use cookies to Store and/or access information on a device. Are you familiar with anything similar on the metallurgy/knife steel side of things? Type 8Cr, the more common formulation, is worse than AUS-8: a little more prone to corrosion and not quite as hard. The biggest factor for cost of knife steel is whether it is produced with conventional ingot technology or powder metallurgy. Here its 8. The D2 steel compares nicely with 14c28n steel in terms of edge retention, as it's quite hard as well. This is a non-powder steel produced by American steel company Carpenter. What makes 1.4116 such a bad performer in regards to toughness on par with ultra high carbide steel like S125V? It richly deserves its reputation for high-quality gained over the years by Sandvik, a Swedish manufacturer of world-renowned steel. 9Cr is the top end of the series and is quite good as good or better than AUS-8. The highest edge retention steel was Rex 121 which was at 70 Rc in combination with lots of high hardness vanadium carbides. CPM154 is a truly superior steel. There are significant differences between them because 14C28N is stainless steel, while D2 steel is a semi-stainless tool steel. This doesnt necessarily mean they have terrible toughness, but they have limitations. But SM100 is not widely available, hard to heat treat and grind, and exceptionally expensive. Oh, thats great, thanks. Each test is done with 3 or more specimens to get a good average. I was struggling to simplify all the Rockwell/Youngs Modulus stuff for readers when I came across your site. A few steels have been added since such as MagnaCut and M398. The steel loses some of the chromium in solution for corrosion resistance to form these fine carbides for hardness. There you said 7.6 for 420HC. So presumably, wear resistance would be in the 3.5-4 range and toughness in the 5.5-6 range. Now 14c28n is IMO the best budget steel out there. Im a woodworker and Im interested in making better performing plane irons and chisels.
