GCr15 Steel

GCr15 steel is a high carbon chromium bearing steel with less alloy content, good performance and wide application. The cold working of the steel is medium in plasticity, the cutting performance is general, the welding performance is poor, the sensitivity to white spots is large, and the temper brittleness is obtained.

GCr15 Bearing Steel

GCr15 bearing steel is used in the manufacture of various bearing rings and rolling elements. For example: making internal combustion engines, electric motors, automobiles, tractors, machine tools, rolling mills, drilling machines, mining machinery, general machinery, and high-speed rotating high-load mechanical transmission bearings. Balls, rollers and ferrules. In addition to balls, bearing rings, etc.
