M2 high speed steel Profile: M2 is molybdenum high speed steel with high toughness carbide of the advantages of small and easy to overheat, it should be strictly controlled quenching temperature, more stringent requirements for heat protection due to its hardness and wear resistance. good, much more difficult to cut materials used in the manufacture of cutting tools .M2 has a large high-speed steel carbide tendentious, so the heat protection more stringent requirements, suitable to withstand vibration and shock loads mold factory hardness:. ≤255HB hardening temperature : 1220-1240 Hardness: ≤63 M2 high speed steel Usage: cold forging dies, precision dies, powder pressing molds, shear modulus, add plastic glass of like. Suitable to withstand vibration and shock loads Die: deep drawing dies, punching die. Metal cutting saw blades, cold heading and extrusion tools. M2 high speed steel chemical composition: Carbon C: 0.80 ~ 0.90 (allowable deviation: ± 0.01) Si Si: 0.20 ~ 0.45 (allowable deviation: ± 0.05) Manganese Mn: 0.15 ~ 0.40 (tolerance: +0.04) Sulfur S: ≤0.030 Phosphorus P: ≤0.030 Chromium Cr: 3.80 ~ 4.40 (allowable deviation: ± 0.05) Ni: to allow the residual content ≤0.30 Copper Cu: to allow the residual content of ≤0.25 vanadium V: 1.75 ~ 2.20 (allowable deviation: ± 0.05) Mo Mo: 4.50 ~ 5.50 (tolerance: Size ≤6, ± 0.05; size> 6, ± 0.10) Tungsten W: 5.50 ~ 6.75 (tolerance: Size ≤10, ± 0.10; size> 10, ± 0.20) Note: According to the supply and demand sides agreement, V's content may be 1.60 to 2.20 on the performance of M2 high speed steel use, what material the material, specifications, density, hardness and other parameters of indicators, the latest market price of M2 High Speed ??Steel, Metal Materials Co., Ltd.
