Is it a “good” design? Estimated toughness by comparing manufacturer’s testing, in combination with the estimated CATRA values, allows us an educated guess for the toughness-edge retention combination for the steels allowing for easy comparison: There is also a trendline, which is simply an averaged line drawn through all of the steels. New comments cannot be posted and votes cannot be cast. M390 has only slightly lower toughness than K390 with similar carbide volume (though K390 was tested at 62 Rc). Knife Category Double Action OTF Blade Steel Bohler ELMAX® or M390 or 204P Weight 3.2 oz Blade Length Depend on the user demands and requirements, one type of steel will look more promising than the others. And the datasheet shows that the toughness of M398 is only about a third of M390, though at somewhat higher hardness: Comparing with other Bohler steels, you can see that the toughness of M398 is quite low. it reduces the amount of “vanadium carbide”, some Bohler-patented high wear resistance steels using niobium instead. He also has a custom heat treat protocol, Your email address will not be published. 4-position. For the steels that we have experimental values for, these predictions are close. Bohler Uddeholm M390. For the steels that we have experimental values for, these predictions are close. S35VN Stahl besteht aus 1,4 Prozent Kohlenstoff, 14 Prozent Chromâ¦ Minor surprises are usually in the area of toughness, in my previous comparison of CATRA edge retention steels usually end up where you expect them to be based on their carbide content.

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. Closed Length. Sure, there is a performance difference I can see that but to justify that much in cost difference? Follow me on Instagram@keithkevinken. Top. So M398 doesn’t appear to be over-performing relative to its composition and carbide content. Jun 29, 1999 . 3.8" long blade, 9.50" overall tip down carry. The other steels in the previous chart such as S110V, S90V, and S125V are relatively different from M398 but are similar when it comes to total carbide volume fraction and level of wear resistance. And for Vanax I showed only the total carbide volume because I didn’t want to add another column for its vanadium nitrides, which are different than vanadium carbides. S35VN D2; EDGE RETENTION: 6/10: 3.5/10: EASE OF SHARPNESS: 6/10: 4/10: CORROSION â¦ Page 1 of 2 1 2 Next > Dec 12, 2017 #1. Enter your email address to subscribe to this blog and receive notifications of new posts by email. Ok so browsing Aliexpress I see some folders marked as either M390 or S35VN â¦. Many steels are high hardness (ZDP-189, M390) and many are high toughness (3V, INFI, and Vanadis 4 Extra) but no steel really matches M4 in its combination of the two. When it comes to a knife, everybody wants a durable, flexible and long lasting product. These comparisons will have a range of accuracy. Roughly comparable steels include S60V, MPL-1 (also called Supracor), and “Elmax2” which is an unreleased, patented stainless steel from Uddeholm that I have named Elmax2 because they haven’t named it. N/A. Uddeholm recently replaced their Vanadis 6 and Vanadis 10 steels with a new Vanadis 8 which was designed to eliminate chromium carbides present in the older versions to improve overall properties. Sure, there is a performance difference I can see that but to justify that much in cost difference? MARKET â¦ M390 exhibits excellent edge retention, corrosion resistance, and high level toughness. KnifeCenter or BladeHQ carry these special production runs or are the Dealers limited to DLT Trading, Bento Box Shop? The Para 3 has the Spyderco compression lock, a full flat ground blade, and killer ergos. Both Bohler and Uddeholm use an unnotched Izod toughness test with a 7 x 10 x 55 mm specimen. Today in this article, you can learn some interesting information about two premium blade steels: CTS-XHP vs. M390.  Kajinic, Alqjz, Robert B. Dixon, and Brian A. Hann. 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%. CPM 15V, known for its excessive amount of wear resistance, has 23-25% carbide volume of all vanadium carbide, while M398 has a full 5% more than 15V. There is no such thing as the best steel, each got their own pros and cons. Therefore, even if a higher impact toughness value is measured I would not recommend heat treating the steel in that way. 3.0 out of 5 stars 2. S90V and S110V are close, however, but with significantly lower carbide volume which could mean that they have superior toughness to M398. Sheath. This premium "super steel" is used in many Benchmade knives and several Hinderer and Zero Tolerance models.  Kajinic, Alojz, Andrzej Wojcieszynski, and Maria Sawford. The steel is only available in Russia right now as far as I know, and the datasheet currently available is in Russian .

Crucibleâs first major stainless [â¦] You can read about why those directions are important in this article on toughness. Right now is a poor time to buy an M390 PM2. $112.45 $ 112. Using the reported carbide numbers from M398 along with other steels we can use a simple equation to predict the approximate edge retention of different steels. 284. Battle Worn Finish!! The end result is that Uddeholm toughness values are somewhat lower than those for Bohler, particularly for low carbide volumes: You can also see that Elmax and Vanax steels underperform the non-stainless trendline of Vanadis 4 Extra (V4E) and Vanadis 8. Microtech Ultratech is a double action, button fired automatic knife. âEyefinityâ Technologie, die je nach Schnittstellen Gegebenheiten die Nutzung von bis zu 6 Bildschirmen simultan er The... $129.95. And M398 has quite a bit less toughness than that: So it is apparent that the design of M398 is all about wear resistance and essentially ignores toughness. Less chromium in solution means lower corrosion resistance, which is confirmed by the corrosion test that they did: So overall, M398 has higher wear resistance and hardness than M390, but lower toughness and corrosion resistance. Para Militaryâ¢ 2 G-10 Black. More carbide means less toughness, so the lower the volume of carbide the better the toughness is. The end result is that Elmax2 has similar toughness to the original Elmax, a fact that surprised the designers of the steel . Spyderco Para Military 3 Sprint Run C223GPFGR, 2.95" CPM S45VN Plain Blade, G-10 Handle. It also performs well with both coarse and highly polished edges. According to some manufacturers and knife makers, the 20CV is the best of the three at holding an edge. The design goal for Uddeholm, Bohler, and Crucible is generally the same for cold work tool steels and stainless steels: maximize vanadium carbide content. It will give you everything you are looking for, but be prepared to pay between $250.00 and $300.00 with the scalpers on eBay. Both are great steels and very close in real life performance, IMHO.

I really do wish M390, CTS204P and Elmax would become standard instead of just sprint runs. For MPL-1 the breakdown of its carbide types is not known, only the total volume, so I assumed all of it is the vanadium-enriched chromium carbide. VS. YouTube *NEW* About 93 13,642 BUY â¢ $325 Release date: Q2 2015. While they have similar histories and composition, there are a few. The bulk Cr content in M398 is the same as M390 but the amount of chromium carbide increased from 18% to 25%, which also tells us that chromium in solution has been reduced. This high-performance alloy offers very high wear and corrosion resistance, yet remains extremely easy to sharpen and maintain. S35VN VS D2. Steels that are above the trendline show a superior combination of properties and those below it have a somewhat lower toughness-edge retention balance. This thing is SO beautiful, and the sheath is as well. Bento Box Shop had their blue exclusive PM2 for something like $195 shipped, DLT Trading did their red exclusive for I think $145. So, eBay would really be a poor choice cause their prices are all over the map. Hope your enjoying this mini series of all the knives that I bought in 2019.
