Bearing Steel

1. Property: Balanced mechanical property, with high and uniform material hardness after heat treatment, good wearing resistance and long service life under frictional environment.

2. Main Application: Bearing components such as rollers and outer ring of bearings; also used for tooling, measuring instrument and other mechanical components which requires high wearing resistance, high elasticity and yield point.

3. Typical Series, Content Elements and Mechanical Property
