Heat Treated Bearing Steel Ball for Precision Ball Bearing

High chrome steel ball introduction:

GCr15SiMn steel is a high-carbon, high-chromium bearing steel, which has higher wear resistance and hardenability than GCr15 steel. The critical quenching diameter in oil is 90~110mm (volume fraction of 50% martensite). After oil quenching at 840°C, tempering at 350°C, and then light quenching, the surface hardness is as high as 1096HV, and the depth of the hardened layer can reach 1mm. In view of the insufficiency of the heat treatment process of the forming roller, the non-martensitic transformation occurs by pre-cooling at the thin edge to produce troostite or sorbite, which enhances toughness, reduces stress, and then quenches as a whole to meet the process requirements.
