W6Mo5Cr4V2Co5(M35) hot rolled steel round bars

W6Mo5Cr4V2Co5 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 has better machinability, but the strength and impact toughness are lower, and it is easy to oxidize and decarburize. W6Mo5Cr4V2Co5 is general Used as gear cutters, milling tools, punches, cutter heads and other tools for cutting hard materials.
