42CrMo Maschinenwelle Schmiede

18Cr2Ni4WA is a high strength of alloy carburizing steel Characteristics: 18Cr2Ni4WA steel alloys in common carburizing steel, strength, high toughness, good harden ability, can not carburized and quenched in the case of the use of large cross-section generally used as the load is high and good toughness, notch sensitivity an important part of the low. Mechanical Properties: Tensile strength σb (MPa): ≥ 1175 (120) Yield strength σs (MPa): ≥ 835 (85) Elongation δ5 (%): ≥ 10 Section shrinkage ψ (%): ≥ 45 Impact energy Akv (J): ≥ 78 Impact toughness αkv (J/cm2): ≥ 98 (10) Hardness: ≤ 269HB
