bearing steel is used to manufacture, steel rollers and bearing rings. Bearing in the work under immense pressure and friction, so they requested bearing steel with a high and uniform hardness and wear resistance, and high elastic limit. The chemical composition of bearing steel uniformity, non-metallic inclusion content and distribution, the distribution of carbides and other requirements are very strict, all steel production in the most demanding steel one. International Organization for Standardization ISO 1976, some of the common into the international standard bearing steel, bearing steel will be divided into: full hardenability bearing steel, hardened bearing steel, stainless bearing steel, high temperature bearing steel and other four categories of 17 steel. Some countries add a category for special purposes, bearing steel or alloy. Have been incorporated into the standard of bearing steel and the ISO classification is similar to correspond to the high carbon chromium bearing steel, carburizing bearing steel, stainless steel, corrosion resistant bearings, high temperature bearing steel four categories. Bearing steel in China is still nearly five decades of steel and bearing materials, such as non-chromium bearing steel, carbon bearing steel, bearing steel, and special purpose alloys, metal ceramics made great progress. GCr15 high carbon chromium bearing steel is the world's largest production of bearing steel, carbon Wc is about 1% chromium Wcr about 1.5%, from 100 years since its inception in 1901, the main component little changed, with the scientific and technological progress, any continuing research, product quality and continuous improvement of the world's total production of bearing steel more than 80%. So now we are talking about bearing steel without special instructions, and that means GCr15
