Introduction:

Bearing steel is the steel used to make balls, rollers and bearing rings. Bearings are subjected to great pressure and friction during work, so bearing steel is required to have high and uniform hardness and wear resistance, as well as a high elastic limit. The requirements for the uniformity of the chemical composition of the bearing steel, the content and distribution of non-metallic inclusions, and the distribution of carbides are very strict. Which play a vital role in improving the performance and long life of the product. Widely used in the manufacture of bearings, automobiles, machinery, aerospace and other fields.
