However, M398 does have some positive traits, such as increased hardness and reduced retained austenite relative to M390: An increase in hardness and reduction in retained austenite makes me believe that the amount of chromium in solution has been reduced, learn why chromium in solution matters for hardness in this article on Vanax steel. In operation since 1998, BladeForums.com has led the industry since Day 1. Grind. However, after all of these comparisons I can’t help but be disappointed that the steel companies appear to still be stuck on very high carbide volume stainless steels when using powder metallurgy. My next step is going to be a custom puukko. They have the ELMAX Version in stock, but the M390 is out of stock or available for pre-order depending on which site. Along the same lines, CPM S45VN has slightly better edge retention in CATRA test results (all % numbers relative to AISA 440C steel ) when compared to S35VN steel , 143% vs, 140%, and slightly worse than S30V steel - 145%. He is a YouTuber from the United States. I really do wish M390, CTS204P and Elmax would become standard instead of just sprint runs. This is a modification of their older PM stainless M390 which was released in the late 1980’s. But the steel is too new to really know yet. And M398 has a relatively poor ratio of vanadium carbide to chromium carbide because of its high chromium content. There is no 3V or Vanadis 4 Extra equivalent stainless steel with lower carbide volume for better toughness. The toughness of S110V was estimated using its reported carbide volume as no toughness numbers are available. It polishes really pretty though, like in the Heat Seeker. FREE Shipping by Amazon . Not really sure what a fair price would be for a new Paramilitary 2 m390 would be? There is no such thing as the best steel, each got their own pros and cons. Decided to get myself a ZT 056xCF. I want the larger version so 0560, 0561,0562. But if Bohler pushes out M398 more broadly it will be interesting to see how knifemakers utilize the steel for applications that benefit from high wear resistance and edge retention. More carbide means less toughness, so the lower the volume of carbide the better the toughness is. Hit like and all that good stuff. Dual "at rest" springs allow for button deployment and retraction of the blade. While steels have their own attributes, it seems the m390 would hold longer edge. Here is a chart of Crucible steels showing the effect of carbide volume on toughness: So the carbide volume fraction is very important for steel design and predicting steel properties. Somewhat surprisingly, however, if the izod toughness of Uddeholm in joules is converted to the ft-lbs of Crucible c-notch charpy toughness test, the values are basically right on top of each other: So if we shift down the Bohler values, and convert everything to ft-lbs, we get a rough comparison of toughness for all of these stainless steels. best. Die Buchstaben âSâ, âVâ und âNâ beziehen sich auf die Begriffe ârostfreiâ, âVanadiumâ und âNiobâ. So many variables come into play with these tests.
