Stainless Steel Passivation

Passivation is a chemical treatment that restores and strengthens the Natural corrosion resistance of stainless steel. During fabrication, machining, and handling, free iron particles, shop dirt, and other contaminants can become embedded in the surface and cause rust spots. Passivation removes these contaminants using a controlled acid treatment (typically nitric or citric acid) and allows a uniform, chromium-rich oxide layer to re-form on the surface. At Balambiga Metal Finishers, we passivate stainless steel components to help them perform reliably in demanding environments.
