GCr15 steel is one of the most commonly used Chinese bearing steels, it’s a high carbon chromium bearing steel with high hardenability, high & uniform hardness after heat treatment, high contact fatigue strength, good dimensional stability and corrosion resistance. The cold deformation plasticity is medium, the machinability is general, the weldability is poor, and it is sensitive to the formation of white spots, and there is a first type of temper brittleness.

Bending of GCr15 bearing steel
GCr15 bearing steel is used to manufacture various bearing sleeves with wall thickness ≤12mm and outer diameter ≤250mm, steel balls with diameters of 25.4-50.8mm; also used for other rolling elements with wide range of sizes, such as tapered rollers, cylindrical rollers, spherical rollers, needle rollers, etc.; also used in the manufacture of molds, precision gauges and other mechanical parts that require high wear resistance, high elastic limit and high contact fatigue strength.
