Stainless Steel Passivation

ASTM 967, AMS 2700

Stainless steel is corrosion resistant by nature, which might lead you to believe it doesn’t need any extra treatments, but the iron in stainless steel actually can corrode in the form of rust. Chlorine or other contaminants can cause the iron to oxidize, showing small spots of rust over time. Stainless steel passivation removes free iron from the surface of stainless steel parts, leaving chromium to oxidize. This makes the surface passive (meaning it doesn’t react with the air) as well as more corrosion resistant.

We use a Citric Acid based passivation bath to be more environmentally friendly and to give parts the perfect treatment.

Benefits of Passivation:

  • Prevents corrosion, oxidation, and pitting
  • Cleans and improves appearance
  • Works with almost any alloy of Stainless Steel


Part sizes are limited by tank size of 31”x23”x18”
