Passivation


Passivation improves the corrosion resistance properties of components made of precipitation-hardened, austenitic, ferritic and martensitic steels. 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 or citric acid without oxidizing salts, will dissolve the imbedded iron and restore the original corrosion-resistant surface by forming a thin, transparent oxide film.


Type of Process Passivation treatments for cleaning and descaling corrosion-resistant parts, components, equipment and systems.
Features For Passivation we adhere to:
  • AMS 2700: Passivation of Corrosion Resistant Steels
  • BAC 5625: Passivation of Corrossion Resistant Steels (Type II)
  • BAC 5751: Passivation of Stainless Steel
  • DPS 9.07: Surface Treatment of Corrosion Resistant Steels
  • GAMPS 4103: Acid Cleaning of Ferrous Alloys
  • GSS 7021: Acid Cleaning of Ferrous Alloys
  • AMS-QQ-P-35-98: Passivation Treatments for Corrosion-Resistant Steel
Material Acid cleaning creates passivating layer a few atoms thick.
Base Materials Worked Steel, Stainless Steel.
Automation All Passivation processes are performed manually to ensure the proper care is given to each step.

Quality Control

All processes are subject to our rigorous Quality Assurance process. All work is reviewed and inspected to be in compliance with the specification (Process Approval requested).
