Passivation improves the corrosion resistance of parts made from 200, 300 and 400 series and precipitation-hardened corrosion-resistant steels by removing soils and free iron.

​

Passivation does not remove heat treat scale. It is usually removed by glass bead blasting. 440C material is not normally passivated. Cleaning by mechanical methods is recommended.

​
