Abstract

The intergranular corrosion (IGC) of eight ferritic stainless steels of 400 series was evaluated by means of test in copper-copper sulfate-16% sulfuric acid and electrochemical-potentiodynamic reactivation (EPR). It was found that carbon content and stabilization elements played an important role for the IGC susceptibility. EPR method was affected by the grain reactivation of ferritic stainless steels, but its accuracy could be improved through surface observation of the tested samples.
