Passivation


What is Passivation?

Passivation is a chemical treatment process that enhances the natural corrosion resistance of stainless steel and other corrosion-resistant alloys. It removes free iron and surface contaminants, allowing a protective oxide film to form and protect the metal beneath.

Note – Stainless Steel Passivation should not be confused with Zinc Passivation.

Where Passivation
excels

Corrosion Resistance

Restores and strengthens the protective oxide layer on stainless steel.

Clean Surface Finish

Removes contaminants from fabrication, machining, or handling.

Non-Dimensional

No measurable build-up — preserves surface finish and tolerances.

Improved Durability

Extends component lifespan in harsh or corrosive environments.

Applications

Used across medical, food processing, aerospace, and marine industries.
