I will be writing a more in-depth history of S30V and S35VN in the future. Its carefully tuned chemistry promotes the formation of more chromium carbides, while leaving larger amounts of free chromium available for corrosion resistance. The Mo content of M390 is lower, however, so it is difficult to predict how things balance out when comparing higher Cr vs higher Mo. If liquid nitrogen is not available then use dry ice, and if neither is available then a freezer is next best. It has Rick Hinderer's well-known Spanto blade, a practical … Vanax – 1975°F (18% carbide/nitride volume). S110V and M390/20CV/204P do have higher Cr in solution than S45VN. CPM S45VN is the updated version of CPM-S35VN. This CPM S35VN stainless steel data sheet highlights the edge retention and toughness of this knife steel. Shop Knives. It also has increased Carbon and a some Nitrogen added to allow for higher hardness than CPM S35VN. 195. The design including niobium and nitrogen additions should help maintain toughness similar to or better than S30V. Toughness really isn’t as important in fixed blades. BNIB. If I ever want to try something in S45VN, I’ll wait until, or if, that steel becomes part of the regular lineup and not a sprint. Blade Hardness: 58-60 HRC. Spyderco Paramilitary 2 PM2 Diamond Arc G-10 S45VN C81GPFGR2 Sprint Run. [1] Chilton’s iron age 226 (1983): p. vi. May 13, 2020 #13. Due to how well rounded it is. ***One per household. Leather sheath included. Vanax has smaller carbides/nitrides than these other steels, however, because it is largely free of chromium carbides and because nitrides coarsen very slowly [7]. But if the edge should get dinged or dulled against bone, all you need to do is mail it in to Benchmade’s popular LifeSharp Service. He describes it as an American made version of Elmax. Instead, a complex chromium carbide is formed which does not have the same high hardness as the pure vanadium carbide. Blade Type. S35VN has better toughness. Quick view Compare Add to Cart.

Along the same lines, CPM S45VN has slightly better edge retention in CATRA test results(all % numbers relative to AISI 440C steel) when compared to CPM S35VN steel, 143% vs, 140%, and slightly worse than CPM S30V steel - 145%. These numbers are calculated using ThermoCalc software: The main changes we expect from S45VN vs S35VN and S30V are an improvement in corrosion resistance due to the increase in Cr of about 1%. Austenitizing at 2000F followed by a Cryo treatment and tempering at 400F should result in a hardness of 61-62 HRC, (507) 720-6063 info@usaknifemaker.com 2650 9th Avenue Mankato, MN 56001. The S45VN chemistry was first introduced by Niagara Specialty Metal’s Western Sales Manager and Knife Steel Specialist, Frank Cox. But not quite up to super steel status m390, s90v, s110v, 4v, m4? Using the ThermoCalc estimated carbide content we can use a previously devised edge retention prediction equation to determine its approximate CATRA edge retention. It was found that in both cases the retained austenite content was relatively low, so even higher austenitizing temperatures would be required to start to see a divide between freezer and liquid nitrogen. Anywho, I really hate that your buying a $300-500 knife and they worry about the amount of grinding belts they go through. Spyderco Bombshell - $424.99. S35vn has been being put into high end folders ($300-700) Chris Reeves, Sparta blades ect…, and I don’t understand the reasoning, But I don’t care for needed to maintain them so rust isn’t as issue. Sold Out CPM® S45VN is a martensitic stainless steel specifically created to transcend its predecessors. Forest Green Diamond Arc G-10 handles. The chemistry has been rebalanced to improve corrison resistance, wear resistance and edge retention. But I suspect further experiments would reveal that its toughness is high due to undesirable factors such as excess retained austenite. I suspect that those samples (austenitized at 2140°F) have relatively high retained austenite which can help with toughness but is not always desirable. Its carefully tuned chemistry promotes the formation of more chromium carbides, while leaving larger amounts of free chromium available for corrosion resistance. However, the datasheet has an asterisk next to the 143% value and says that it is “based upon market feedback.” These estimates should perhaps be treated with some suspicion as the S35VN datasheet has the same asterisk for its 145% value which puts it at the same level as S30V, but independent experiments put S35VN around 132% at 61 Rc [8]. Read about the effect of niobium in steel in this article. Everyone loves a Gunny! A new Para 3 Sprint Run from Spyderco Knives dressed in Diamond Arc textured, Forest Green G10 and outfitted with a satin finished, plain edge CPM S45VN stainless steel blade.

If you buy 1, you will get a stick 12" long by the width and thickness shown. Crucible researchers used the same 14% Cr as S90V to best utilize the vanadium additions but also sought to improve corrosion resistance through an increase in molybdenum. Eventually though, CRK introduced S30V steel, which Chris was directly involved … So using niobium instead of vanadium should lead to a refined microstructure in general in part because of modifications to solidification as well as reducing the amount of chromium carbide. [8] https://knifesteelnerds.com/wp-content/uploads/2018/08/Bohler-Uddeholm-CATRA.pdf, Awesome article gonna have to get some now. Nitrogen is not as prone to form chromium nitrides as carbon is to form chromium carbides, so nitrogen can often be added to steel for an increase in hardness without decreasing corrosion resistance. CPM-S45VN steel for improved wear resistance and corrosion resistance : ... MSRP: $279.95. Based on the toughness testing result, I think a higher austenitizing temperature than the 1950°F recommended in the datasheet is best. However, with the relatively high amount of vanadium and niobium in S45VN the nitrogen is not actually in solution. CPM S45VN is the updated version of CPM-S35VN. The nitrogen addition is not made to S35VN [5], but it has returned for S45VN. ... Sep 3, 2008. As noted in the niobium article, small additions of niobium can also improve toughness by refining the microstructure as a whole by changing the sequence of solidification. New to Benchmade, the CPM-S45VN premium stainless steel provides the perfect balance of a fine grain, sharp edge with carefully engineered blade flex. When m390/20cv/204p seems to be a superior steel to it overall. The equation puts S45VN at about 142% at 61 Rc, very close to the value provided by Crucible. But there are going to still be much better steels for the job in regards to folding knifes. The 2000°F austenitize led to an improvement in both hardness and toughness relative to the 1950°F austenitize recommended in the datasheet. Relatively high hardness can be achieved with a 300°F temper, in the 63-64 Rc range. The peak in hardness is generally seen around 15% retained austenite.
