Passivation

Overview

For stainless steel components, the passivation process protects against corrosion and oxidation. During the passivation a transparent film forms on the surface of the component. This film occurs naturally on stainless steel, but the film occurs uniformly and quickly through the passivation process.

The passivation process is determined by the part geometry. A full range of passivation methods are provided to meet the requirements of the industry and industrial standards. As this is a process that finishes safety critical and high reliability components, a fully staffed chemistry lab continuously monitors the passivation process at every step. Inspection and testing are performed to ensure that the passivation process is complete and the parts are free of surface defects.

 

Key Performance Properties of Passivation:

  • Protects against corrosion
  • Protects against oxidation
  • Returns stainless steel or other metals back to its original
    specifications
  • Improves and purifies the surface of the part
  • Does not change the outward appearance of the base metal

  • QQ-P-35
  • AMS-QQ-P35
  • ASTM A 967
