Though stainless steels are generally corrosion resistant, their corrosion resistance is significantly lowered under the following conditions.

• Embedded foreign material during manufacturing
• Sulfide added stainless steels for improved machinability
• Iron or ferrous particles from cutting tools on the machined surfaces

Stainless steel passivation removes the contaminants and grows the oxide surface back. This restores the original corrosion resistance of stainless steels.

Non passivated machined stainless steel surfaces can seriously impact chemical reactions and affect the processed product color.

We adhere to the AMS 2700 Specification and offer both Citric and Nitric Passivation.
