42CrMo4 Alloy Structural Steel Bar

42CrMo4 Alloy Structural Steel Bar

42CrMo4 is used to manufacture forgings that require higher strength and larger tuning cross-section than 35CrMo steel, such as large gears for locomotive traction, supercharger transmission gears, rear shafts, connecting rods and spring clips with great loads, 42CrMo4 can also be used for drilling pipe joints and fishing tools in deep oil Wells below 2000m.

Mechanical properties Tensile strength σb (MPa) : ≥1080(110) Yield strength σs (MPa) : ≥930(95) elongation δ5 (%) : ≥12 Section shrinkage ψ (%) : ≥45 Impact work Akv (J) : ≥63 impact toughness value αkv (J/cm²) : ≥78(8) Hardness: ≤217HB
