Passivation of Stainless Steel

The passivation process involves the removal of iron or iron compounds from the surface of stainless steel by chemical dissolution, a treatment with an acid solution that will remove the surface contamination without significantly affecting the stainless steel itself. These contaminants are potential corrosion sites that result in premature corrosion, that ultimately result in deterioration of the component if not removed.

 

Metal passivation is the chemical treatment of stainless steel with a mild oxidant, such as a nitric acid solution, for the purpose of enhancing the spontaneous formation of the protective passive film. Ultimately, passivation is a combination of both cleaning, as well a protective coating.

We provide passivation to a number of specifications. One of the most common Specifications is QQ-P-35C, but take a look at all of our approvals here.
