Advantages: Extremely high wear resistance and corrosion resistance. level 1. Although it is officially MT24 (Mule Team 24), it leapfrogged the MT23 to get it into users’ hands faster. Thank you for the very detailed write up! I used 4 specimens for each condition and these were machined by me. To check your heat treatment against mine, it is best to perform heat treatments from a range of austenitizing temperatures and going straight into the cold treatment used, whether freezer, dry ice, or liquid nitrogen. Regarding the vanadium being insufficent for grain refinement. Retaining the intuitive and strong compression lock, the Para 3 is a reliable EDC tool that will offer all day comfort at just 3.4 ounces. Notify me of follow-up comments by email. Peter Bruno of New Jersey Steel Baron provided me the following information on the steel: Nitro-V Data. The ATAC, designed by legendary custom maker J.A. New comments cannot be posted and votes cannot be cast. 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.

Maxamet’s distinguishing metallurgical characteristic is the high carbon content (2.15%) and the inclusion of 10% Tungsten. Very nice wtriteup, greatly appreciated. $206.50. I have cut off the lines where peak hardness was achieved in each. Required fields are marked *. The blade of this remarkable knife is crafted from Böhler-Uddeholm M390 particle metallurgy stainless steel. Pro-Tech recently put out the first new batch of the Harkins ATAC dual action autos in years. Calculations of chromium in solution from Thermo-Calc confirms that the two are similar, especially when considering that Nitro-V needs to be austenitized at a somewhat lower temperature. I next produced toughness specimens using the 1950°F austenitizing temperature plus cryo but tempered at 300 and 450°F to test the effect of tempering temperature. $205.00. It will be interesting to see what sort of a premium these new versions will command. You can read more about the history of AEB-L, 13C26, and 14C28N in this article. The full flat grind is relatively thin behind the edge (between 0.020-0.025” depending on where along the belly you’re checking), and has a gradual flat face that terminates at the spine. How does 14C28N compare in toughness and edge retention? I don’t know if a 400°F temper would see similar results. No price has been announced for either the Maxamet Manix 2 or Native 5. If they make a G10 maxamet I was unaware. 14C28N, however, has significantly more chromium in solution, which likely gives it better corrosion resistance than Nitro-V and AEB-L. Nitrogen can also help improve corrosion resistance, when it comes to pitting it has 16 times the contribution of chromium. The compositions of the two are similar and the micrographs also look very similar in terms of carbide content. 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. The drawbacks here are, again, sharpenability. We are all familiar with the surface voids produced in concrete when a stone from… AEB-L has edge retention similar to 52100, which is significantly lower than higher carbide content stainless steels like 440C, CPM-154, S30V, etc. The blade shape, a clip point in most spec sheets, has a nice gradual belly, and a very flat spine, once you’re past the *sharply jimped* thumb ramp. That said, S30V is a great steel! Carbides in steel are often compared to gravel in concrete. Spyderco Pochi Kazuyuki S45VN Titanium Frame Lock Folder C256TIP ... Spyderco SpyOpera Brown Canvas Micarta Satin M390 Back Lock Folder C255CMP . Therefore Nitro-V would be well suited to knives requiring good toughness. Spyderco Sage 1 Cool Gray G10 Satin Maxamet Liner Lock Folder C123GPGY . It's cool to carry a knife made from Maxamet, M390, or CPM-S110V. If you are interested in trying out Maxamet but can’t wait for the Manix or Native, the MT24 is still available for purchase. The 300°F temper led to increased hardness with a reduction in toughness, as expected. AEB-L and Nitro-V have a similar volume of carbide, approximately 4-6%. Nitro-V does indeed look very similar to AEB-L, having the same C, Cr, and Si along with a minor difference in Mn. This shows how good Maxamet is at this one particular thing. KnifeNews delivers today's news for knife people like us. The 1850°F austenitized led to reduced toughness relative to the 1900 and 1950°F conditions. The ParaMilitary 2 has a blade shape, grind, and spine thickness (0.15”) that all comes together in a very simple looking manner. Zome is a traditional Japanese dyeing technique, and the Seki-City facility has adapted this process for the Delica and Endura production processes. Buy Spyderco Manix 2 Lightweight Signature Folding Knife with 3.37" CTS BD1 Black Steel Blade and Black FRCP Handle - PlainEdge - C101PBBK2: Pocket Knives & Folding Knives - FREE DELIVERY possible on eligible purchases 2) there is more scatter in results at higher values. “We also did extensive scientific testing on Maxamet’s performance, edge retention, and toughness and found that it easily rivaled the very best steels we’ve ever used,” they say.
