The corrosion behaviors of stainless steels and Ni base alloys in a FGD plant are discussed. Electrochemical and immersion tests were performed to investigate the behavior of corrosion, especially pitting corrosion. The performance of corrosion resistant alloys was evaluated for the higher chloride concentrations in the FGD Plant.
