Bearing steel has high hardness, tensile strength, contact fatigue strength and wear resistance, and considerable toughness, which meets the requirements for corrosion resistance and high temperature resistance under certain conditions.
The high carbon chromium bearing steel has a high carbon content (0.95-1.05%), high and uniform hardness can be obtained after quenching, and a long fatigue life. The disadvantage is that it is slightly less resistant to large loads and impact toughness.
High-carbon chromium bearing steel is mainly used as the rings and rolling elements of rolling bearings under general conditions of use.
Bearing steel balls, as an important part of the bearing, play a very critical role.
Therefore, the use effect and service life of the bearing are closely related to the accuracy and hardness of the bearing steel ball. The hardness of the bearing steel ball is related to the crushing load value of the steel ball.

The biggest feature of the bearing steel ball is its high hardness and wear resistance. Then we need to be frequently exposed to the hardness value of the steel ball. The hardness value range of the finished steel ball is specified in the national standard of steel ball GB/T 308.1-2013.
