M390

M390 – Bohler M390 Microclean. Third-generation powder metallurgy technology steel. Developed for knife blades requiring good corrosion resistance and very high hardness for excellent wear resistance. Chromium, molybdenum, vanadium, and tungsten are added for excellent sharpness and edge retention. Hardens and tempers to 60–62 HRC, where it best balances edge holding and toughness. Due to its alloying concept, this steel offers extremely high wear resistance and high corrosion resistance.
