M2 is molybdenum steel mold steel, high speed steel,commonly known as the wind, 6542, has the non-uniformity of carbide and higher toughness advantages. Easy tooverheating, it should be strict control of quenching temperature, the heat treatment protective requirements more stringent. Because of its hardness and good wear resistance, used for the manufacture of cutting hardertool.M2 die steel cutting materials with carbide tendency is larger, so the heat treatment protective requirements more stringent, suitable for die withstand vibration and shockloads.

Factory ability ≤ 255HB

Hardening temperature 1220-1240

Hardness ≤ 63

Main uses

Cold forging die, precision die, powder pressing dies, shearmodulus, adding glass fiber plastic mould etc.. For mouldwithstand vibration and shock load: deep drawing die,punching die. Metal cutting saw blade, cold forging andextrusion tools etc..
