42CrMo4 is an industrial material belonging to the alloy structural steel series. 42CrMo4 has high strength, hardenability, good toughness, small deformation during quenching, and high creep strength and lasting strength at high temperature. 42CrMo4 steel is an improved variety of American AISI standard 4140 steel. The steel has good machinability, easy polishing, easy to bite, and can be electroplated.

42CrMo4 is used to manufacture forgings that require higher strength and larger quenched and tempered sections than 35CrMo steel, such as large gears for locomotive traction, supercharger transmission gears, rear axles, connecting rods and spring clips that are heavily loaded. 42CrMo4 is also used. It can be used for drill pipe joints and fishing tools in oil wells below 2000m.
