This is a very similar, though not identical, ratio to S30v, though M390 has a larger overall carbide structure. The structure of the metal on a metallurgical level, or the microstructure, has more chromium carbide than vanadium carbide. This means that while the vanadium content does increase the hardness of the steel, it does not add as much ... M390 Steel: Elegant, High-end, And Fine-edged. Just like the N690, the M390 was developed by Böhler-Uddeholm. Bohler M390 steel is considered one of the finest and toughest knife steels to date. The M390 was developed to make parts of jet engines with it. This alone can be a statement of the toughness of the M390. M390 hardens to 60-62 HRC. The following hardness values came from heat treating small coupons with a 20 minute austenitize, plate quench, liquid nitrogen cryo, and tempering twice for two hours each time. An S90V CATRA knife I heat treated with 2050-400 resulted in 61.7 Rc, within range of the above values. However, the toughness specimens measured about 1 Rc lower.This is my first time heat treating A-2 tool steel. What I find interesting about A-2 tool steel is that it air hardens, meaning you do not need to quench in... Jan 08, 2016 · Heat treating O1 tool steel is simple. In short, bring it to critical temperature, quench it in vegetable oil, then temper it in an toaster oven or regular kitchen oven for one hour at 400˚.
