Application:

 

Used in the manufacture of high strength, large cross-section forgings such as supercharger transmission gear,rear axle,hummar shank etc.

 

 

42CrMo has the characteristic of high strength, hardenability, good toughness, low deformation in quenching, high creep strength and endurance.

It can used in the manufacture requirements higher than 35Crmo steel strength and conditioning section more large forgings, such as locomotive traction with the big gear, supercharger drive gear, pressure vessel, rear axle, gear load connecting rod and a spring clip, can also be used to under 2000 m deep well of oil drill pipe joint and the fishing tool, and can be used for bending machine mould, etc.
