Passivation removes the free irons and other materials following forming, welding, or machining operations. If left untreated, these contaminants can adversely affect the condition of the surface resulting in premature corrosion and decreased mechanical performance.

We passivate per ASTM A380, ASTM A967, SAE AMS2700 and QQ-P-35. We use Citric or Nitric per customer’s request.
