Process Overview

Passivation is a chemical surface treatment process used to enhance the corrosion resistance of stainless steel by removing free iron and contaminants from the surface.

During the process, parts are treated with a mild acid solution that promotes the formation of a stable and protective oxide layer. This passive layer significantly improves resistance to rust, oxidation, and environmental damage.

Passivation is widely used in industries requiring high cleanliness and corrosion resistance, such as medical devices, food processing, and precision engineering.
