We are offering the high quality Passivation Tank for effective use in the various commercial and industrial applications. Passivation is a widely-used metal finishing process to prevent corrosion. 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. Passivation is a chemical treatment for stainless steel and other alloys that enhances the ability of the treated surfaces to resist corrosion. The Passivation Tank is very efficient and safe for use.
