Passivation

Engineered for Maximum Wear Resistance and Surface Strength

Passivation Services for Stainless Steel Corrosion Resistance

GMF’s passivation process removes surface contaminants from stainless steel and restores its corrosion-resistant oxide layer. Using validated nitric and citric chemistries, we meet the strictest specs for aerospace, medical, and industrial applications — with every load tested and documented.

Why Passivation Matters

Stainless steel can lose its corrosion resistance during machining, welding, or handling. Passivation is essential to restore its protective oxide layer. Our controlled process:

Removes free iron and other surface contaminants

Enhances long-term corrosion resistance

Leaves no dimensional change or visual alteration
