    Your Guide to Stainless Steel Passivation

    Nitric acid-based passivation is one of the most basic passivation techniques out there. Here, the stainless steel wire or sheet metal is dipped in a bath of oxidizing nitric acid. This mild acid bath removes some free iron molecules and other foreign matter from the surface of the steel while encouraging the development of the passive oxide layer. Citric Acid Passivation Solution for Stainless Steel Citric acid passivation is the use of citric acid to passivate stainless steel (SS) and other alloys to prevent corrosion. By removing free iron ions and forming a protective passive oxide layer on the surface, the stainless steel or other metal becomes highly resistant to rust.
