Nitric Passivation


This process consists of immersing stainless steel components in a solution of nitric acid without oxidizing salts, will dissolve the imbedded iron and restore the original corrosion-resistant surface by forming a thin, transparent oxide film.

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.

Advantages of Nitric Passivation

•Maximum stainless steel corrosion protection without plating.
•Superior clean surface.
•Eliminates iron contamination reactions with other materials.
•No rust discoloration.
