Corrosion of Stainless Steel: Test Methods and Proper ...

Oct 01, 2017· Stainless steels – naturally corrosion-resistant metal alloys – are auto-passivating, which means they spontaneously produce a passivation layer (a thin passive film) in oxidizing environments like air or moisture. The passivation layer is non-reactive: it inhibits the electrochemical reactions that would normally take place between the base material and the environment.
