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, and it is one of the most stringent steel types in all steel production.Bearing steel has high and uniform hardness and wear resistance, as well as high elastic limit.
