W6Mo5Cr4V2 M2 high speed tool steel round bar
M2 is a molybdenum series high-speed steel known for its small carbide inhomogeneity and high toughness. It offers excellent hardness and wearability, making it ideal for manufacturing cutting tools for difficult-to-cut materials. Due to its tendency to overheat, strict control of quenching temperature and protective heat treatment are required.
