42CrMo Tool Steel



Material Name


Material Name: 42CrMo

Characteristics and scope of application


High Strength and hardenability, good toughness, quenching deformation small, high temperature with strength and high creep rupture strength. For making greater demands was higher than that of 35CrMo steel strength and conditioning section of forgings, such as locomotive traction gear, supercharger drive gear, pressure vessel gear rear axle by load greatly and the connecting rod and the spring clip, for below 2000m deep oil drill pipe joints and fishing tools, and can be used for bending machine die.
