42CrMo4 steel is an industrial material. 42CrMo4 steel is used to manufacture forgings with higher strength and larger quenched and tempered section than 35CrMo steel, such as big gear for locomotive traction, transmission gear of supercharger, rear shaft, connecting rod and spring clamp under great load. 42CrMo4 steel can also be used for drill pipe joint and fishing tools in oil deep wells below 2000m.
42CrMo4 steel executive standard: EN 10083 / 3-2006
Characteristics: 42CrMo4 steel has high strength, hardenability, good toughness, small deformation during quenching, high creep strength and rupture strength at high temperature.
42CrMo4 steel is an American AISI standard 4140 steel improved variety. The steel has good machinability, easy polishing, easy biting and electroplating.
