Bearing steel ball material related requirements and material distinction Jun 11, 2018

Bearing steel ball is a kind of steel ball made of bearing steel. The materials used to make the bearing steel ball are those with relevant requirements, specifically GB/T18254-2003 and GB/T3203-1982. The former is a high carbon chromium bearing steel, and the latter is a carburized bearing steel. . Among these two standards, GCr4, GCr9, GCr15, etc. can be used to manufacture bearing steel balls.


For bearing steel and plain carbon steel, it can be distinguished from two aspects of strength and hardness. The strength and hardness of these two steels are generally tested. If the strength and hardness are both large, then it is the bearing steel.
