The steel with the most stringent production requirements -bearing steel

Bearing steel is the steel used to make balls, rollers and bearing rings. Bearing steel has high and uniform hardness and wear resistance, as well as high elastic limit. The requirements for the uniformity of the chemical composition of bearing steel, the content and distribution of non-metallic inclusions, and the distribution of carbides are very strict. It is one of the most stringent steel types in all steel production.

①Strict chemical composition requirements.
②Higher dimensional accuracy requirements

③Specially strict purity requirements.
④Strict low-magnification tissue and microscopic (high-magnification) tissue requirements.
⑤Specially strict requirements on surface defects and internal defects.

⑥Strict carbide unevenness requirements.
⑦Strict surface decarburization layer depth requirements.
⑧In the bearing steel material standards, there are also strict requirements for the smelting method, oxygen content, annealing hardness, fracture surface, residual elements, spark inspection, delivery status, marking, etc. of the bearing steel.
