Product Description

Product Description

Bearing steel is used to make balls, rollers and bearing rings. Bearing steel has high and uniform hardness, wear resistance and high elastic limit. The requirements for the uniformity of chemical composition, the content and distribution of non-metallic inclusions, and the distribution of carbides of bearing steel are very strict. It is one of the most stringent steel grades in all steel production. In 1976, the International Organization for Standardization (ISO) incorporated some general bearing steel grades into the international standards, and divided the bearing steel into four types, namely, fully hardened bearing steel, surface hardened bearing steel, stainless bearing steel, and high temperature bearing steel, with 17 steel grades.
