Passivation process is a method of removing free iron from the surface of stainless steel. Passivation also improves the corrosion resistance properties to improve the surface condition of stainless steel. By immersing stainless steel components in a solution of citric acid, it dissolves iron that may have imbedded as a result of grinding, machining or other manufacturing operations. If allowed to remain, the iron can corrode and give the stainless steel an appearance of rust. In dissolving the imbedded iron, passivating restores the original surface by forming a transparent oxide film.

At TMF we offer passivation to ASTM A967. Certificates of compliance are provided upon request.
