Abstract
Abstract The corrosion behavior of duplex stainless steel 2205 DSS and 2507 DSS in simulated flue gas condensate of a waste incineration power plant at 180 °C was compared by micro-area electrochemical testing, surface and weight loss analysis. The results showed that the corrosion resistance of the two stainless steels decreased with the increase of Cl− concentration. After 48 h of corrosion, when the Cl− concentration was not less than 6 g·L−1, active sites where current density increased suddenly appeared on the surface of 2205 DSS, accompanied by the obvious increase of surface roughness and the weight loss. The lowest Cl− concentration that caused the appearance of active sites on the surface of 2507 DSS was 20 g·L−1, with less surface corrosion products and lower degree of general corrosion.
