AbstractZhanjiang is a typical industrial Marine atmosphere environment and there are large amounts of Cl- and SO2 contained in atmosphere. These two constituents contribute to the corrosion of carbon steel Q235, pipeline steel L415, pressure vessel steel 16MnNi at the Zhanjiang oil station. In this study, a wet-dry cyclic accelerated experiment was carried out to study the difference in corrosion behavior of three type of steels under Cl- and SO2. The results indicated that the empirical formula D = At-n was suitable for corrosion kinetics of three materials. At the same exposure time and under the same corrosion conditions, the corrosion degree of three materials was: carbon steel Q235 > pipeline steel L415 > pressure vessel steel 16MnNi. There were the same corrosion products of three materials, and the corrosion degree was determined by the relative content of alpha-FeOOH and gamma-FeOOH. Additional, Cl- was found to play a decisive role in the corrosion rate.
