What is EN 42CrMo4 equivalent Chinese steel 42CrMo plate

42CrMo plate is Chinese steel material, equivalent to European EN 42CrMo4, Japanese JIS SCM440,  American AISI 4140, etc.. With high strength, high toughness, good high temperature strength, good machinability, medium cold bending plasticity, high hardenability, good welding performance and so on advantages, EN 42CrMo4 equivalent Chinese steel 42CrMo plate is suitable for manufacturing driving gear, rear axle, engine cylinder, drill pipe joint and fishing tool of oil deep well, etc..

Mechanical properties of 42CrMo plate:
Yield strength σs (MPA): ≥ 930 (95)
Tensile strength σb (MPA): ≥ 1080 (110)
Elongation δ5 (%): ≥ 12
Impact energy Akv (J): ≥ 63
Impact toughness value αkv (J / cm2): ≥ 78 (8)
Hardness: ≤ 217HB
Reduction of area ψ (%): ≥ 45

EN 42CrMo4 equivalent Chinese steel 42CrMo plate is used in the quenching and tempering state, which enables it to get high fatigue limit and multiple impact resistance.
