Also Mo additions improve corrosion resistance for a given amount of chromium. Many custom makers enjoy AEB-L, as its easy to machine but still has a high hardness, around 62 HRc. ApexUltra is a steel that we are working on that had excellent properties in small batch production (50 lbs). Different companies can vary some between each other making the same product, while a single company is going to be more consistent. AEB-L and 14C28N are the best in the high toughness group. Each steel was tested with a knife that was produced just for the test, and then sharpened the same way for each test (15 dps 400 grit CBN sharpening). you can easily buy a $500 knive made out of 14c28n, which has nothing in it besides cr and a trace of ni. Thats a pretty large difference in two budget steels that are often compared to each other. Sandvik 14C28N steel is better than D2 steel in corrosion resistance and toughness. Is Vancron SuperClean a good choice for a chef knife? All of the experiments shown below are possible thanks to supporters. It is an excellent steel that in the right hands has proven to produce high performing blades. Alloying elements are an important ingredient vital in getting the best steel for the job. have extremely high edge retention. 14C28N steel is as a result of a more corrosion resistant version of the 13C26 steel. Would be great if some manufactures changed their steels based on this information. Hello LARRIN, do you have a Rough estimate on when ApexUltra (as well as more Magnacut) will become available? I was guessing 5.5 based on your rating of CPM-154. 14C28N knife will dull faster, but it is easy to sharpen. just recently the idea occured tome to sharpen a planer blade like a knife and check out how it performs. Opinel Number 9 in carbon steel, and a Cold Steel Tanto Lite in their stainless steel. Custom maker Brian Trudeau uses Nitro V, and Massdrops Perpetua design is the first production knife to sport it. This is about comparing steels to each other rather than a limitation of an individual steel. I was thinking maybe Sleipner or A2 would be best if a PM steel was out. AEB-L and 14C28N also have moderate edge retention though of course much lower than vanadium-alloyed powder metallurgy steels like S30V or M390. What makes 1.4116 such a bad performer in regards to toughness on par with ultra high carbide steel like S125V? H1 and 420 also have excellent corrosion resistance but are limited to lower hardness and edge retention. CPM 4V Knifemakers use dozens of steel types to create knife blades. 14C28N knives are better than D2 knives in corrosion resistance. So, its hard steel is easy to sharpen. But in my experience, it has been nothing but great. Though technically not a stainless steel at least 14% chromium, and D2 usually has 12% its relatively corrosion-resistant. 2. The material increase machinability and strength. 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. YMMV It can dull your edge, cause pitting, and damage the structural integrity of your knife. and yet millons of knives are being made out of 1.4116 (aisi 420mov?) Thanks Larrin, Thanks again for everything you're doing, it's a tremendous resource. If you are a newbie, sharpening D2 knives will be a struggle, but it is doable with practice and the right sharpening tools. Using controlled furnace heat treating resulted in toughness around 23-28 ft-lbs at 61-62 Rc, while the knifemaker heat treated specimens were 7 ft-lbs or below. You can see micrographs of different knife steels to compare their carbides in this article. Micarta 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. Uddeholm lists it as somewhat worse in toughness than A2 but somewhat better in wear resistance. SG2 Can you contact me via my email address so I can send you a copy in PDF and epub. Almost all of the knives in my EDC rotation are Spydercos, in exotic steels. European steel company Sandvik produces 14C28N, a non-powder metallurgy steel. But if you want to know what the coolest blade material is, for my money, SM100is it. Is there some way we might predict the relative "effective toughness" of different steels at different hardness and at different edge angles? Thanks to Bill Smutz, Alex Topfer, Florian Bachler, Brunhard, Art, Rod H, Sach, Jinny Koh, Jon Duda, Cory Henderson, and UPKnife for becoming Knife Steeel Nerds Patreon supporters! Because of the material difference, the blades differ in toughness, edge retention, corrosion resistance, and ease of sharpening. Poor availability may effectively increase cost of steel. Oh, thats great, thanks. 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. Read more. On the positive side, they are very easy to forge and grind. The knives are ideal for both indoor and outdoor use. It has excellent edge retention, corrosion resistance, and ease of sharpening. Question. ZDP-189 can tarnish, though not as easily as 3V. And easy to sharpen in our experience; and that will get an excellent razor edge that lasts for a reasonable price of time. 14C28N. By that I dont mean that a better heat treatment is not possible, but that major mistakes in heat treating are avoided. in relation to hardness). I have a bachelor's degree in Mechanical engineering with a specialization in material science. Diving into the pool of knife personalization possibilities is a fantastic way to fend off the post-knife-buy blues. In the context of a knife this would be chipped edges or broken knives. The high hardness makes it all but impossible to sharpen and machine. But its very cheap, and, when ground appropriately, it can be a real winner from a value standpoint. Having 1.5% Carbon does that. When describing the characteristics of a steel, a few common attributes are commonly talked about. It applies to both of course, hence why there isnt a separate label. CRKT and Spyderco use BD1. Theres also a line of green triangles a bit below that. Its a good balance between all three attributes, being relatively hard, tough, and corrosion-resistant. AEB-L GiantMouse Vox/Anso ACE Iona Liner Lock Knife, Muley Freaks Erik Van Woerkom Charged With Felony Possession of Trophy Mule Deer, The Biggest Improvement to My Camp Kitchen Is a Mini Pizza Oven (But Not for Pizza), Propane Traeger, Moosejaw Coolers, Hybrid HOKAs, Adventure Chess, and More Emerging Gear, Avalanche Outside British Columbia Resort Buries 10, Kills 3 Heli-Skiers, Netflix Unveils First Trailer for Tour de France Series. Not to sound like a ship, but these two knife inspiration makes this an eye-catching knife. However, it can be somewhat complicated because an edge can dull from many causes wear, micro-chipping, deformation, or corrosion. Austenitizing is the process where the steel is heated to high temperature prior to quenching (rapid cooling) to harden the steel. Any idea where it would be on the hardness and toughness scales? Sorry, most of my previous comment was borderline word salad. Due to its higher Chromium content, S30v is a lot less likely to corrode/rust than the D2 Steel. And while youll find it mostly in expensive knives, quite a few approachable M390 blades exist. It mainly made for knife and it high in Chromium for excellent corrosion resistance. 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. Its hard to imagine a more rust-inducing environment than saltwater and fish guts. and our I have a question about the chart You can read about my CATRA edge retention testing in this article. All Rights Reserved. Vanax gives up some toughness and hardness vs MagnaCut for saltwater levels of corrosion resistance. On the other hand, edge stability in terms of micro chipping and edge folding is also good. (I think the 420HC estimate in that post was based on simulation or computer modeling, since you didnt spray testing any of the 400 series.) It shows 3 stainless steels from 750-800tcc but the edge retention graph only has 1 SS in that range, S90v. The line is only in the neighborhood of 5 of the datapoints. Heres The Best Review For You (2021), D2 knife blade offers high edge retention, Dulls faster, Requires frequent sharpening. Although it should be noted that there doesnt seem to be a need for the stainlessness on a wood working tool. However, Kershaw asked Sandvik to make their 13C26 steel more resistant to corrosion, and the result was 14C28N. there seems to be an optimal procedure for every alloy (provided its heat treated to industial standards). The most balanced is CPM-MagnaCut which is in an area all by itself on the chart. Corrosion is not only cosmetic. And before you start arguing on behalf of the steel you think might be perfect, let me remind you that if your knife isnt perfect for a task, youll need to get another one that is! The brand designed it as a carbide replacement. 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. Cool! And Michael Fitzgerald, Tim Marais, and Head VI for increasing their contributions. Display: 24 per page Sort by: Featured View CIVIVI Voltaic Flipper Knife Stainless Steel Handle With Micarta Inlay (3.48" 14C28N Blade) $88.30 Add to cart On the other hand, 9cr18mov has a slightly higher molybdenum content which gives it higher hardness from quenching and helps drive carbide formation. Other factors that can be added in are corrosion resistance, hardness, and cost. 1. Both steels are popular among knife manufacturers and both have their strengths and weaknesses. I know it's much more stainless and corrosion resisitance, but what about wear resistance? So setting edge geometry for the type of knife and intended use is very important. Also how did you arrive at the edge retention & toughness numbers for 8cr13mov and for BD1N toughness? 14C28N, designed by Sandvik at Kershaw's behest to have the edge properties of 13C26 but with increased corrosion resistance by adding nitrogen and chromium. Is there a reason SG2/R2 are not included in the lineup, despite being one of the most popular ones? Alpha Knife Supply sells 26C3 btw. This is also a powder-metal steel produced by American steel company Crucible. However, Kershaw asked Sandvik to make their 13C26 steel more resistant to corrosion, and the result was 14C28N. G10 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. Type 8Cr, the more common formulation, is worse than AUS-8: a little more prone to corrosion and not quite as hard. Furthermore, because of its ultrahigh hardness, Maxamet is very prone to corrosion, probably worse than 1095. Oftentimes steels that are reported to be difficult to sharpen are in fact improperly heat treated and challenging to deburr. and get better and longer-lasting performance? The edge retention numbers are normalized to the hardness of the closest toughness test. To view the purposes they believe they have legitimate interest for, or to object to this data processing use the vendor list link below. Even though it has very high hardness, its also still decently resistant to corrosion and quite tough. Reddit and its partners use cookies and similar technologies to provide you with a better experience. Moreover, the blades will serve you longer because they do not wear out faster with frequent use and sharpening. If you look at the chart you may notice that at high toughness levels if you increase edge retention by only a relatively small amount you get very big drops in toughness. Steels with very high vanadium content like Vanadis 8, CPM-10V, K390, CPM-15V, etc. Distilled water can separate steels that are stainless vs those that are not. We did the research to help you find the best hunting knife for your needs and budget. Its not bad, but you can find better in the market at the same price. Note:There is a powder-metal version called CPM154 thats purer than the non-powder version, making it easier for knifemakers to grind. As such, the performance of the steel is entirely dependent upon the steels being utilized. The big difference in properties vs the low alloy steels, however, are the harder carbides that are found in these steels. Note:Dont bother with anything less than 8Cr in this series. This is the steel used in Swiss Army knives and is excellent for beginner sharpeners. Your email address will not be published. looking at getting a nice larger flipper for a little under 100 AUD. Developed by New Jersey Steel Baron, Nitro V is a non-powder steel marketed as an enhanced version of AEB-L. Nitro V, as its name indicates, adds nitrogen to AEB-Ls formula to make the steel even more corrosion-resistant. There are a lot of different types of steel out there . 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.
