First, the material of stainless steel bearings has strict chemical composition requirements. Under normal circumstances, stainless steel bearing steel is mainly high-carbon chromium stainless steel, only by strictly controlling the chemical composition of stainless steel, can its structural properties and hardness be guaranteed.

Secondly, the dimensional accuracy of stainless steel bearings, stainless steel bearing rings are generally forged. If the dimensional accuracy is insufficient, it is difficult to calculate the blanking size and weight very accurately, so the quality of stainless steel bearing parts cannot be guaranteed. May cause damage to equipment or mold.

Third, the purity of stainless steel bearing materials. Generally, if stainless steel bearings contain more impurities, it will seriously affect their service life. Therefore, if you want to ensure the service life and reliability of the bearing, you must reduce the content of non-metallic inclusions in the steel as much as possible.

In addition, there are many other requirements. One of these requirements is the requirement for a decarburized layer on the surface of the steel. In general, if the surface decarburization layer of the steel exceeds the specified range, it should be removed before heat treatment, otherwise stainless steel bearing parts may be scrapped.
