What is Passivation? How Does Stainless Passivation Work?

Passivation is a non-electrolytic finishing process that makes stainless steel more rust-resistant. The passivation process typically uses nitric or citric acid to remove free iron from the surface. This results an inert, protective oxide layer that is less likely to chemically react with air and cause corrosion.What is stainless steel passivation? - The Rust StoreWhat is stainless steel passivation? Passivation is the process of treating or coating a metal in order to reduce the chemical reactivity of its surface. In stainless steel, passivation means removing the free iron from the surface of the metal using an acid solution to prevent rust.
