How the stainless steel passivation process works
The passivation process of stainless steel is a chemical treatment that improves the corrosion resistance of stainless steel by forming a dense, stable oxide film (usually chromium oxide, Cr2O3) on its surface. Passivation not only restores the passivation film of stainless steel that has been damaged during processing and welding, but also further enhances its corrosion resistance. The following
