Material Name
Material Name: 15Cr
Characteristics and scope of application
This kind of steel is mainly used in the manufacture of high working speed and section is small (less than or equal to 30 mm), but the heart requirements higher strength and toughness and wear resistant surface carburized parts, such as gears, cam, valve, piston and sleeve, and a crank pin, piston pin, piston ring, coupling, a shaft, a bearing ring. In addition, the steel can also used as a low carbon martensite quenching steel, used for manufacturing of deformation is not strict, but requires strength and toughness of parts
