This premium "super steel" is used in many Benchmade knives and several Hinderer and Zero Tolerance models. Trader. 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%. Right now is a poor time to buy an M390 PM2. Microtech Ultratech is a double action, button fired automatic knife. DLT is smack dab in the middle of the exclusives market and has brought out some of the hottest models over the last few years such as the Paramilitary 2 Red G-10 M390 Blade and the Paramilitary 2 Tan 20CV blade series. The high Cr is significant in part because it reduces the amount of “vanadium carbide” that is present in the steel as opposed to “chromium carbide.” The vanadium carbide is harder and therefore contributes more to wear resistance and edge retention. Clip Position. The S35VN or CPM S35V is a high-end martensitic stainless steel made by @Crucible, high in Carbon, Vanadium, and chromium designed to offer a great balance between toughness, hardness and corrosion resistance.Itâs used in long-wearing Specialty cutlery, Plastic Injection and Extrusion Feed Screws and Dies, Wear Components for Food and Chemical Processing, and of course in the Knife Industry. Thanks! S30V is reported to be about 145%, Elmax about 142%, and M390 about 179%: Bohler-Uddeholm CATRA results. Alberta Ed. While steels have their own attributes, it seems the m390 would hold longer edge. Bohler has recently released a new stainless powder metallurgy steel – M398, I first learned about it here. 3.8" long blade, 9.50" overall tip down carry. PM2s in M390 were dealer exclusives only, so market dictates their prices. Compression. However, the Elmax2 steel seems to do as well as the high carbide Vanadis 60 high speed steel. 390 390X Fury-X Fury Nano. See the datasheet here. More carbide means less toughness, so the lower the volume of carbide the better the toughness is. To show the stark difference here are some non-stainless Crucible PM steels overlaid on the above chart: I’m personally not all that interested in yet another high edge retention steel that sacrifices toughness, ease in sharpening, and workability. Therefore, even if a higher impact toughness value is measured I would not recommend heat treating the steel in that way. Hinderer XM-18 3.5" Stonewashed S45VN Spanto OD Green G10 Bronze Tri-Way Flipper 0974 . Triple handmade.com has a super trapper in M398 for sale on his site. Hit like and all that good stuff.

Below I will use the available information to come up with as good a comparison we can with other stainless steels in its class. 67,037 â¦ It’s not cheap though. It is also easier to machine and polish than CPM S30V.  Maili, I., R. Rabitsch, W. Liebfahrt, H. Makovec, and E. Putzgruber. Benchmark your GPU here. The toughness of S110V was estimated using its reported carbide volume as no toughness numbers are available. 17 comments. Vanadium carbide gives more wear resistance for a given amount of carbide, and the total carbide content controls toughness to an extent. S45VN is a king when it comes to field sharpening. Henrysears February 11, 2020 Blog No Comments. S90V, S110V, and S125V appear to offer a superior combination of properties to the new M398. 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.  Sadberg, Odd and Lennart Jonsson. a mix) of carbon and iron that is often enriched with other elements to improve certain characteristics depending on the desired application. Larrin, best. And M398 has a relatively poor ratio of vanadium carbide to chromium carbide because of its high chromium content. M390 exhibits excellent edge retention, corrosion resistance, and high level toughness. I know there are tougher and more wear resistant steels, with alloys hardened to a higher degree, but the ability to sharpen in the field is something that should be taken into consideration. 390 390X Fury-X Fury Nano. Bird & Trout CPM S45VN Blackwater 2 Elmax Bloke X Bloke X V2 Bloke Z V2 Boone 1 A2 Bravo 1 A2 Bravo 1 Custom Köcher-Scheide Bravo 1 Custom Sabot Scheide Bravo 1 Field A2 Bravo 1 LT CPM 3V Bravo 1.2 A2 (German Edition) Bravo 1.5 A2 Bravo 1.5 LT CPM 3V Bravo Necker 1 CPM 154 Bravo Necker 2 CPM 154 BRKCA Knife 2017 CPM 3V Brokk A2 Brunox Lubri-Food Bush Seax Bantam A2 â¦ The more carbide a steel has the better the wear resistance and the worse the toughness is. 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. Today in this article, you can learn some interesting information about two premium blade steels: CTS-XHP vs. M390. Decided to get myself a ZT 056xCF. 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. So we can understand more the Steel, letâs see its chemical composition. However, the datasheet has an asterisk next to the 143% value and says that it â¦ S45VN is a new powder metallurgy stainless steel being produced by Crucible that has just been announced.

Post by nirvanero » Sat Jan 30, 2016 1:08 am M390 is usually cheaper, easier to sharpen and has more corrosion resistance than S90V. 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. You can read more about powder metallurgy and its history in this article. We would expect this to lead to a significant reduction in toughness along with an increase in wear resistance. The M390 sprint looks to have been ideal, but sounds like S35VN still would be easier to sharpen. The... $129.95. from Knifecenter.com - The Original and Largest Online Catalog of Cutlery RWL34 is easier to sharpen but doesn't hold an edge as well as the other two in general, especially M390 (assuming proper heat treatment across all of them). CPM S35VN is a martensitic stainless steel designed to offer improved toughness over CPM S30V. S35VN is a premium steel and M390 is considered a super steel. The S45VN datasheet provides a number for CATRA edge retention relative to 440C, which it lists as 143%. Der Hauptunterschied liegt in der höheren Reinheit des Pulvers und einer erheblich geringeren Partikelgröße. Alongside edge geometry and design, blade steel is a critical element that determines how a knife performs. We could simply predict based on carbide volume alone, but that would be too easy. Bento Box Shop had their blue exclusive PM2 for something like $195 shipped, DLT Trading did their red exclusive for I think $145. M398 was a relatively simple modification of M390 and I can’t help but think that a more optimized version could be made. United States. CPM-S45VN is a martensitic stainless steel specifically created to transcend its predecessors. Hope that this helps. “High chromium and carbide rich tool steel made by powder metallurgi and tool made of the steel.” French Patent filed January 1, 2003. New comments cannot be posted and votes cannot be cast. Kershaw Knockout 1870CFM390 Carbon Fiber M390. The lower chromium content of those steels means they have more vanadium carbide rather than chromium carbide, so they are expected to have similar edge retention with lower carbide volume. 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. Performance profile from 325,102 user samples. Like ELMAX, it is just as tough as, if not tougher than, S35VN, and can hold an extremely strong and sharp edge. All of the values are relative to 440C at 58-59 Rc which would be “100” on the chart: Carbide values from . Kershaw Knockout 1870CFM390 Carbon Fiber M390.  Pinnow, Kenneth E., William Stasko, and John Hauser. The Bohler toughness values can perhaps be compared to Uddeholm if shifted down to compensate for the difference in direction. 258,065 User Benchmarks. Toughness Test K390 vs Cruwear vs S110V. However, Bohler does this test in the “longitudinal direction” while Uddeholm does the test in the “transverse direction.” Those directions are relative to the direction the steel is rolled.

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. In choosing the best pocket knife you should pay particular attention to the type of steel used in the blade. 15:35. I saw a Youtube rope test video between the two blade steel's and I tell you what. 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. So it all comes down to the personal preference and working conditions of the knife. Those steels would be breaking new ground and potentially offering new property combinations not previously available. "The reason that the somewhat better toughness result for 20CV and M390 is puzzling is because of the significantly coarser carbide structure. So, eBay would really be a poor choice cause their prices are all over the map. Dual "at rest" springs allow for button deployment and retraction of the blade.

Similar hardness to S90V in the patent. They have the ELMAX Version in stock, but the M390 is out of stock or available for pre-order depending on which site. I am not seeing a huge difference that would justify the cost difference between the two. Required fields are marked *. Depend on the user demands and requirements, one type of steel will look more promising than the others. To estimate how the toughness compares between Bohler (M390 and M398), Crucible (S30V, S90V, S125V, S145V, S60V, MPL-1, and S110V) and Uddeholm (Elmax, Elmax2, and Vanax) we need to see how the different toughness tests compare. 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. SPEED â¦ S35VN VS M390. Tungsten was very expensive and only available to mine in Ok so browsing Aliexpress I see some folders marked as either M390 or S35VN â¦. It’s hard to say since it’s never existed as a commercial product. Benchmark your GPU here. Sep 9, 2018 #7. Are these "Exclusive Dealer Runs" ever announced beforehand? Poor: 37% Great: 52%. The change in composition is primarily an increase in vanadium, from 4% to 7.2%, with a corresponding increase in carbon to maintain the same level of hardness after heat treatment. CPM S30V. The finer structure of S45VN would be expected to lead to better ease in machining and sharpening and better â¦ I wrote about some Bohler-patented high wear resistance steels using niobium instead that look very interesting but haven’t seen a commercial release. I am not seeing a huge difference that would justify the cost difference between the two. S35VN VS D2. Sheath. So in terms of maximizing the wear resistance-toughness balance we don’t expect M398 to break any new ground. Three knives available today. M398 is low because it has a very large volume of carbide of mostly chromium carbide. Lowest price in 30 days. 2002. N/A. 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. : S30V/S35VN or S110V or M390 .
