 42CrMo4 Steel Introduction 

42CrMo4,42CrMo4 Steel, Alloy Structural Steel

42CrMo4 steel is  is characterized by good hardness and high strength, hardenability, deformation is little when be quenched, high creep and rupture strength at high temperature, generally intended for fabrication of quenched and tempered, flame or induction hardened machine parts.
42CrMo4 Steel Delivery state
42CrMo4 Steel Material should be delivered at Q+T (quenched and tempered) conditions.
42CrMo4 Steel Application
42CrMo4 steel is generally intended for fabrication of quenched and tempered, flame or induction hardened machine parts.
