Passivation (AMS-QQ-P-35)

The Passivation process is a method of removing metal oxides; heat-treat scale and other foreign materials from stainless steel, leaving the surface chemically clean and prepared for further processing. Passivation restores the original corrosion-resistance surface by forming a thin, transparent oxide film on the part. Parts that are to be soldered or brazed should be Passivated before, but not after, these operations.
