Bearing steel has a high and uniform hardness and wear resistance, as well as a high elastic limit. The chemical composition uniformity of bearing steel, the content and distribution of non-metallic inclusions, and the distribution of carbides are very strict, which is one of the most strict steel grades in all steel production.
Bearing steel is used to manufacture ball bearings, roller, and sleeve steel can also be used to produce precision measuring tools, cold die, machine screws, such as die, measuring tools, taps, and precision parts of diesel engine oil pump.
