Stainless steel bearing quality what are the requirements for steel

Stainless steel bearings have been used in more and more industry and so on the market of stainless steel bearing more and more multifarious, many customers think that as long as is stainless steel bearings are the same, in fact is not the case, the stainless steel bearing on market actually variable quality, good and bad difference is very big, with the stainless steel bearing steel used by have the very big relations. In the production of stainless steel bearings, want to consider the characteristics of stainless steel bearing should possess, therefore in the process of manufacturing, quality requirements for the steel than ordinary industrial steel strictly a lot, mainly includes the following three aspects: first, the chemical composition of stainless steel bearing materials have strict requirements. Typically, stainless steel bearing steel high carbon chromium stainless steel, only the strict control of chemical composition of stainless steel, to ensure the performance of organization and hardness. Second, the dimensional precision stainless steel bearing steel, stainless steel bearing ring is generally after forging forming, if lack of dimensional precision, it is difficult to accurately calculate the discharge of the size and weight, which makes it impossible to guarantee the quality of stainless steel bearing parts, could also lead to the damage of equipment or the die. Third, the purity of the stainless steel bearing material, usually, if the stainless steel bearing contains impurities more, then will seriously affect its service life. Therefore, if you want to guarantee the service life and reliability of the bearing, then it must be as far as possible to reduce the content of non-metallic inclusions in steel. In addition, it also includes many other requirements. In these requirements, one is to the requirement of steel surface decarburization layer. Usually, if the steel surface decarburization layer within the prescribed scope, you should clear out before heat treatment, otherwise will may lead to scrap stainless steel bearing parts.
