Surface Treatment

Passivation

Passivation can be selected according to corrosion resistance, conductivity, appearance, assembly, and customer standards.

Finish Overview

Passivation is commonly used on stainless steel parts to improve corrosion resistance by cleaning and stabilizing the surface without changing the basic appearance significantly.

Surface treatment should be selected together with the base material, service environment, appearance target, corrosion resistance, and assembly requirement.
