Passivation is the chemical treatment of a stainless steel surface with a mild oxidant such as a nitric acid or citric acid solution. This is typically done to remove any foreign material from the surface of the metal which enhances the corrosion resistance of the stainless steel surface and accelerates the re-formation of the passive layer.

Used with orthodontic, orthopedic and surgical equipment as well as by industrial, marine and aircraft manufacturers.  Additional passivation applications include high purity water storage tanks, manifolds and pipe spools.
