maxamet vs m390

Bohler calls this steel “Microclean” and it can be polished to achieve a true mirror. SALE* $339.95 $209.95 Nitro-V is a stainless steel sold by New Jersey Steel Baron which was first released in 2017 [1]. Thank you for the very detailed write up! Both AEB-L and Nitro-V reach about 64 Rc, while 14C28N reached 63.5 Rc, though I didn’t austenitize high enough with 14C28N to see where the hardness begins to decline. 100% Upvoted. Nitrogen is not as prone to form nitrides with chromium as carbon is to form carbides. Bohler M390, CTS-204P, and CPM-20CV are all essentially the same steel and sport a near identical composition. That said, S30V is a great steel! Choose Options. All-Around: M390, CTS-204P, and CPM-20CV ... Maxamet is one of two current high-hardness kings, with HRc marks in the high 60s approaching 70, a … For heat treatment experiments on Nitro-V I austenitized for 15 minutes at 1850, 1900, 1950, and 2000°F followed by plate quenching and then immediately going into liquid nitrogen for an hour. New Spyderco Releases Just Put CTS Maxamet Super Steel on the Map, Tungsten contributes to the harden-ability, Millit Knives Stepping into the Spotlight in 2017, The X5 Flipper Breaks New Ground for Hogue, Sal Glesser Shares a Piece of Spyderco History on the Forum, ESEE Expands S35VN Lineup to Include Model 4, The 3rd Annual KnifeNews Readers’ Choice Awards are Here. In stainless steels, the amount of retained austenite for a given amount of carbon in solution (hardness) is how much chromium is in solution (corrosion resistance). WTS--Spyderco Mule blades (MAXAMET, K390, S110V, CTS-XHP and Cobalt Special) Prices reduced ... Not to be confused with the more popular M390, but has a great deal more edge retention. Carbides in steel are often compared to gravel in concrete. One question: you write that Nitro-V has “slightly” lower toughness than AEB-L, but if I read the graph right AEB-L has a toughness about a third greater at around HRC 61 (~33 ft-lbs vs ~22 for Nitro-V). Para™ 3 G-10 Digital Camo Black Blade. I recommend cryogenic processing for maximizing strength when heat treating. The ParaMilitary 2 has a blade shape, grind, and spine thickness (0.15”) that all comes together in a very simple looking manner. I believe that Nitro-V and AEB-L are both available up to 1/4″ so unless all of that is sold out thickness shouldn’t need to be a deciding factor. If you are interested in trying out Maxamet but can’t wait for the Manix or Native, the MT24 is still available for purchase. Para™ 3 Lightweight Black Blade. Another obvious comparison is with 14C28N which was designed as a version of 13C26 modified for improved corrosion resistance. Nitro-V has very good toughness compared with other steels. If they make a G10 maxamet I was unaware. MAXAMET VS M390 The M390 offers better toughness, corrosion resistance and it’s a bit easier to sharpen compared to the Maxamet, but for the edge retention Maxamet is the best. Spyderco Para 3 Maxamet, S110V, M390 bonus LT Wright Bushcrafter HC. Your email address will not be published. best. New comments cannot be posted and votes cannot be cast. This high-performance alloy offers very high wear and corrosion resistance, yet remains extremely easy to sharpen and maintain. This Paramilitary exclusive is sure to turn heads with its red G-10 handle and all-around good looks all while performing like an all star with Bohler-Uddeholm’s M390 super stainless steel. The nitrogen addition, however, did not increase chromium in solution for enhanced corrosion resistance and the vanadium addition was insufficient for grain refinement according to simulation software. I have previously shared a micrograph of Nitro-V that I took along with 41 other steels. Zome is a traditional Japanese dyeing technique, and the Seki-City facility has adapted this process for the Delica and Endura production processes. Nitro-V is expected to have very similar wear resistance and edge retention to AEB-L, but there has not been any testing to confirm that. Typically such small additions of vanadium are for the purpose of grain refinement in low alloy steels. Folding Knives with M390 Steel Automatic Knife Ordering Agreement IN COMPLIANCE WITH FEDERAL STATUTES , KnifeCenter, Inc requests that you read carefully the requirements set forth below, and agree to this prior to your purchase or receipt of any automatic opening knife from our company. Doug Ritter RSK® MK1-G2 Knifeworks Exclusive - Black / Stonewashed. However there are a couple things that led me to make that statement: It has slightly lower toughness than AEB-L for unknown reasons. Choose Options. But I can’t recommend tempering higher than 350°F right now because I don’t know where the reduction in toughness takes place. But, it’s not easy to work with, and few knife makers have been able to rise to the challenge of machining, grinding, and sharpening it. Check hardness and austenitize no higher than the peak hardness. In this section, we’re going to compare our steel with other steels, and for this, I use four criteria; Edge Retention, Corrosion resistance, Ease of Sharpness, and Toughness, and I use a scale or note from 1 to 10. Maxamet is made by Carpenter Technology, a company best known among steel snobs for its CTS-XHP, which made appearances on the Spyderco Techno, Slysz Bowie, and Chaparral among others. Yesterday, Spyderco announced that the Maxamet Manix 2 will be available by the end of the month, and the Maxamet Native 5 by the end of the year. Therefore the vanadium is likely doing very little in Nitro-V. Like other stainless steels Nitro-V has high hardenability so it can be cooled in air or plate quenched for hardness.
