Incotec Passivation is the removal of exogenous iron or iron compounds from the surface of stainless steel by means of a chemical solution. Typically this is done with an acid passivation solution that will remove the surface contamination but will not significantly affect the stainless steel itself.
Passivation treatments improve the surface condition of stainless steel by dissolving iron that has been imbedded in the surface during forming or machining. If allowed to remain, the iron can corrode and give the appearance of rust spots on the stainless steel.
Passivation, which consists of immersing stainless steel components in a solution of nitric acid, will dissolve the imbedded iron and restore the original corrosion-resistant surface by forming a thin, transparent oxide film.
Incotec has continually improved the process over the years and uses a proprietary formula of state-of-the-art methods to strictly adhere to the requirements of AMS 2700.
