What is bearing steel
release time:2018/11/12 12:17:10
Bearing steel is steel used to make balls, rollers and bearing rings. Bearings are subjected to extreme pressure and friction during operation, so bearing steels are required to have high and uniform hardness and wear resistance, as well as high elastic limits.
The uniformity of the chemical composition of the bearing steel, the content and distribution of non-metallic inclusions, and the distribution of carbides are all very strict, and it is one of the most demanding steel grades in all steel production.
China's standard bearing steel classification method is similar to ISO ,which is divided into four categories: high carbon chromium bearing steel, carburized bearing steel, stainless corrosion resistant bearing steel and high temperature bearing steel.
In the PSYZC plant, we chose the high-carbon chromium bearing steel GCr15 with carbon Wc of 1% and chromium content of 1.5%.
