Description

42CrMo4 grade steel is a versatile low alloy steel that possesses good tensile and shock resistance properties combined with ductility.

Its resistance to wear can be considerably increased by flame hardening or nitriding (for maximum wear and abrasion resistance).

Bars can be supplied in quenched and tempered condition with tensile strength exceeding 800 N/mm2 (depending on section thickness) but are also available in the softened, more machineable state suitable for further heat treatment.

Size Range

32mm - 860mm Dia

Typical applications of 42CrMo4 grade steel

  • Axle shafts
  • Crankshafts
