Stainless Steel Units

Stainless Steels Stainless steel materials are used to make bearing components because it is more resistant to surface corrosion due to the higher content of chromium (~18%) with the addition of nickel. The chromium reacts with oxygen to form a layer of chromium oxide on the surface, creating a passive film. Martensitic Stainless Steel- AISI 440C
