Do you know what standard steel can be used to make bearings?

Bearing steel is a type of steel used in the manufacturing of ball bearings, roller bearings, and bearing rings. It is characterized by high and uniform hardness, wear resistance, and a high elastic limit. The chemical composition of bearing steel, as well as the uniformity, non-metallic impurity content and distribution, and carbide distribution, are subject to stringent requirements, making it one of the most rigorously demanded types of steel in all steel production. In 1976, the International Organization for Standardization (ISO) included some common bearing steel grades in international standards, categorizing bearing steel into four types: through-hardened bearing steel, surface-hardened bearing steel, stainless bearing steel, and high-temperature bearing steel, totaling 17 steel grades.

Performance Requirements of Bearing Steel:

To meet the performance requirements of rolling bearings, the following basic performance requirements are placed on bearing steel materials:

High contact fatigue strength,
After heat treatment, it should have high hardness or be able to meet the performance requirements of bearing usage,
High wear resistance and low friction coefficient,
High elastic limit,
Good impact toughness and fracture toughness,
Good dimensional stability,
Good rust resistance,
Good cold and hot working properties.
Bearings endure tremendous pressure and friction during operation, necessitating bearing steel with high and uniform hardness, wear resistance, and a high elastic limit. The requirements for the chemical composition of bearing steel, non-metallic impurity content and distribution, and carbide distribution are extremely strict, making it one of the most demanding types of steel in all steel production.
