Construction Steel 42CrMo4

Construction Steel 42CrMo4

42CrMo4V+QT alloy steel

• Characteristics and scope of application:

High strength, hardenability, good toughness, small deformation during quenching, high creep strength and lasting strength at high temperature.

Used to manufacture forgings requiring higher strength and larger tempered cross sections than 35CrMo steel, such as large gears for locomotive traction,

Supercharger transmission gear, pressure vessel gear, rear shaft, connecting rod with maximum load and spring clamp,

It can also be used for drilling pipe joints and fishing tools in deep oil Wells below 2000m, and can be used for bending machine molds.
