What are the requirements for stainless steel bearings for steel quality?


First of all, stainless steel bearing materials have strict chemical composition requirements. Under normal circumstances, stainless steel bearing steel is mainly high carbon chromium stainless steel, only strict control of the chemical composition of stainless steel, can guarantee its texture and hardness.

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

Third, the purity of stainless steel bearing materials, usually, if the stainless steel bearings contain more impurities, it will seriously affect its 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. Among these requirements, one of them is the requirement for the decarburization layer of the steel surface. Normally, if the decarburized layer of the steel surface is outside the specified range, it should be cleaned before heat treatment, otherwise stainless steel bearing parts may be scrapped.
