M2 Steel is a molybdenum-based high-speed steel with the advantages of small carbide inhomogeneity and high toughness. It is easy to overheat, so the quenching heating temperature should be strictly controlled, and the heat treatment protection requirements are relatively strict.

Due to its good hardness and wear resistance, it is mostly used to manufacture tools for cutting difficult-to-cut materials. M2 steel has a greater tendency to carbide, so it has stricter requirements for heat treatment protection and is suitable for molds that withstand vibration and impact loads.
