In stainless steel, the passivation process uses nitric acid or citric acid to remove free iron from the surface. The chemical treatment leads to a protective oxide layer that is less likely to chemically react with air and cause corrosion. At Inline design the standards we follow are ASTM A967, ASTM A380 and AMS 2700.
