W6Mo5Cr4V2Co5 (M35) is a tungsten-molybdenum series general cobalt-containing high-speed steel. Compared with W6Mo5Cr4V2, it has improved red hardness and high temperature hardness, improved wear resistance, and better machinability, but lower strength and impact toughness. It is prone to oxidation and decarburization.
