Passivation of Stainless Steel

The complete array of metal finishing services available at Master Finish Company includes passivation of stainless steel. Through passivation, the full corrosion-resistant qualities of stainless steel are restored through the chemical treatment of the surface with a mild oxidant.

Iron deposits and other foreign materials are left on the surface of the stainless steel in the course of metal fabrication. These deposits, whether loose or imbedded in the surface, provide breaks that can allow corrosion to begin. In passivation, a chemical bath removes surface contaminants, providing a chromium-rich, corrosion-resistant surface finish.
