Corresponding author : WU Hong- yan, E-mail: wuhy @ ral. neu. edu. cn) Abstract: Corrosion e olution of Mn-Cu w eathering steels in a simulated industrial atmosphere en ironment w as studied by w et/ dry cyclic accelerated corrosion test and electrochemical test . T he results show ed that the corrosion rate increases w ith the w et/ dry cycles in the initial stage of the test and decreases in the latter stage of the test. The corrosion rate of w eathering steel is near to SPA-H steel and lower than that of 16M n steel. In the early, the corrosion rate of fine grain w eathering steel is faster than that of coarse grain, and the corrosion rate is the same in the latter.
