Evaluation of Anti-Weathering Performance of Different Construction Steels by in-Door Cyclic Corrosion Tests Original Research Article

Anti-weathering performance of the fire-resistant construction steel WGJ510C2, produced by Wuhan Steel, was investigated by in-door accelerated cyclic corrosion test (CCT), which is compared with the performance of conventional construction steels Q235 and Q345 studied by a compound circulation corrode testing. It was found that the corrosion speed and corrosion acceleration of WGJ510C2 is obviously lower than that of Q235 and Q345. It can also be summarized that the anti-corrosion performance is closely related to the chemical compositions.
