Product advantage
Characteristic
Chrome steel balls has excellent surface finish, demonstrate high hardness, resistance to deformation, and excellent wear characteristics. Our chrome balls are manufactured from the highest quality chrome alloy steel and after heat treatment for maximum strength and service life.
Application
Chrome steel balls are widely used in precision ball bearings, automotive bearings, motor bearings, precision instruments, household appliances, transportation, etc.
Product background
Bearing steel ball as a precision bearing parts, in the actual work under great pressure and friction, so bearing steel is required to have high and uniform hardness and wear resistance, as well as high elastic limit. The uniformity of chemical composition, the content and distribution of nonmetallic inclusions and the distribution of carbide of bearing steel are very strict. Bearing steel is also known as high carbon carbon steel, carbon Wc is about 1%, carbon Wcr is 0.5% to 1.65%. Bearing steel is divided into six categories: high carbon bearing steel, non-carbon bearing steel, carburized bearing steel, stainless bearing steel, medium and high temperature bearing steel and anti-magnetic bearing steel.
