 M2 tool steel, M2 mold steel, M2 high speed steel tool steel 

 M2 is a molybdenum tool steel with carbide heterogeneity of the advantages of small and high toughness. Easy to overheat, it should be strictly controlled quenching temperature, the heat protection requirements more stringent, because of its hardness and wear resistance, used for more difficult to manufacture cutting tool cutting material. M2 tool steel with carbide greater tendency, so the more stringent requirements for thermal protection, suitable to withstand vibration and shock loading of the mold. 
 Factory hardness ≤ 255HB 
 Hardening temperature 1220-1240 
 Hardness ≤ 63 
 The main purpose of M2 High Speed ??Steel 
 Cold forging die, precision die, powder pressing molds, die cutting machine, add the glass of the plastic mold and so on. Suitable to withstand vibration and shock loading of the mold: deep drawing die, punching die. Metal cutting saw blade, cold heading and extrusion tools. 
 M2 high speed steel chemical composition: C0.95 ~ 1.05, Cr3.75 ~ 4.50, W5.50 ~ 6.75, Mo4.50 ~ 5.50, V1.75 ~ 2.20, Co ≤ 0.50, P ≤ 0.03, S ≤ 0.03, N ≤ 0.08, O ≤ 0.015, Ar ≤ 0.05ppm
