- Vanadium: 1.75%-2.20%
- Molybdenum: 4.50%-5.50%
- Tungsten: 5.50%-6.75%
M2 Steel Properties:
- The hardness of original: ≤255HB
- The temperature of quenching: 1220℃-1240℃
About the heat treatment of M2 steel:
- Anneal: Heat it until the temperature at the range of 800℃ - 850℃, then make it cold slowly.
- Quenching: Heat it until the temperature at the range of 1160℃ - 1220℃, then do the job of oil quenching.
- Tempering: Heat it until the temperature at the range of 550℃ - 580℃, then use the way of air cooling.
Cold forging die, fine die, powder pressing die, etc., shearing die, adding plastic mold of glass fiber. Suitable for vibration and impact loads: deep drawing dies and punching dies. Metal cutting saw blades, cold heading and extrusion tools.
