HS6-5-2 W-Nr 1.3343 Tool Steel A600 M2 UNS T11302 Special Steel
Product Information
M2 is a molybdenum based high-speed steel, which has the advantages of low carbide heterogeneity and high toughness. It is easy to overheat, so the quenching heating temperature should be strictly controlled, and the heat treatment protection requirements are strict. Due to its excellent hardness and wear resistance, it is mostly used for manufacturing tools for cutting difficult to cut materials. M2 high-speed steel has a strong tendency to carbonize, so it has strict requirements for heat treatment protection, and is suitable for molds that withstand vibration and impact loads.
