Bearing steel is the steel 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 types in all steel production. Bearing steel, also known as high carbon chromium steel, has a carbon content WC of about 1% and a chromium content WCR of 0.5% - 1.65%.
