42CrMo4 Hard Chrome Plated Piston shaft

Product Details

What is 42CrMo4 Hard Chrome Plated Piston shaft?

42crmo4 is an industrial material. 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 can also be used for drilling pipe joints and fishing tools for oil deep wells below 2000m.

Chromium plated piston rod is a high-precision steel pipe material processed by cold drawing or cold rolling.
