Given that 80CrV2 has almost no carbide in it after heat treatment, the wear resistance of 80CrV2 is controlled almost exclusively by its hardness. This means that its wear resistance as measured by a CATRA edge retention test is very low on the chart. Steels with more carbide can do muc...

The heat treatment process is important in improving the rolling contact fatigue (RCF) life of GCr15 bearing steel by changing the microstructure. The conventional heat treatment process of GCr15 bearing only has one quenching (CQ) process, and the corresponding RCF life cannot satisfy the requirem...
