Abstract： Hydrochloric dew point corrosion (DPC) behavior of 304 and 316L stainless steels was investigated using a novel DPC simulation set-up with in situ measurements of electrochemical impedance spectroscopy and electrochemical noise. The results indicated that the DPC resistance of 316L stainless steel was superior to 304. The difference of the corrosion performance for the two stainless steels can be ascribed to the following two aspects: the ratio of Cr/(Cr+Fe) is higher and the concentration of Fe is lower in the passive film of 316L stainless steel. There exists Mo in the passive film, which can enhance its pitting resistance of 316L stainless steel.
