Bearing material chrome steel composition and structure

Chrome steel is also known as high-carbon chrome-axial steel, with carbon content of c being about 1%, while cr containing chromium is 0.5-1.65%. Bearing steel is also divided into high carbon chrome bearing steel, non-chrome bearing steel, carburized bearing steel, stainless bearing steel, medium high temperature bearing steel and anti-magnetic bearing steel.


High carbon chromium bearing steel GCr15 is the world's largest production of bearing steel, carbon Wc is approximately 1%, Wcr chromium content is approximately 1.5%, since 1901 more than 100 years, the main composition is basic has not changed, with the progress of science and technology, the research work on, continuously improve product quality, accounting for over 80% of the total world bearing steel production. So that the bearing steel, if there is no special specification, is referred to as GCr15.

China has produced high carbon chrome stainless bearing steel, the main steel number is 9Cr18; Carburized bearing steel with G20CrMo as its main steel number; Chrome bearing steel, the main steel number is GCr15.
