Cold drawn seamless steel spheroid's annealed tube for materail of bearings

Bearing steel is used to manufacture the ball, roller and bearing steel. Bearing the pressure and friction greatly at work, so the required hardness and wear resistance of high and uniform bearing steel, and high elastic limit. The chemical composition of bearing steel, non uniformity of content and distribution of carbides, inclusions distribution and other requirements are very strict, is one of the most stringent requirements of all steel in steel production. In 1976, the international organization for standardization of ISO will be some general bearing steel into the international standard, the bearing steel is divided into: full hardened bearing steel, surface hardened bearing steel, stainless steel, high temperature bearing steel and other four categories of 17 steel name.
