The corrosion resistance performance of different carbon content weathering steels were investigated by cycle immersion corrosion test, rust layer micro-analysis and electrochemical impedance spectra techniques. The results show that the corrosion resistance performance is enhanced with decreasing carbon content of weathering steel. And the corrosion potential of rust layer becomes more positive, corrosion current density decreases, the anode dissolution of rust layer is impeded and the rust layer have more protect performance for test steel with decreasing carbon content of weathering steel.

The ultra-low carbon high strength weathering steel was trial manufactured. By Optical micrographs observation, scanning electronic microscope (SEM), transmission electronic microscope (TEM), accelerated corrosion test, the corrosion resistant performance of test steel and CortenB steel were studied. The results showed that yield strength, tensile strength, elongation and -40 °C impact energy of test steel reached 510MPa, 600MPa, 22% and 115J, respectively. Corrosion resistance of test steel was superior to that of CortenB. The microstructure of ferrite and bainite, quickly forming adhesive dense rust layers to improve the corrosion resistance of test steel.

By testing the mechanical properties, microstructure observation, accelerated corrosion test, the effect of alloying element nickel on microstructure and properties of weathering steels was studied. The results showed that nickel content from 0 to 0.44%(mass percent)have little influence on microstructure and mechanical properties of weathering steels.The corrosion resistance enhanced with increasing nickel content, and nickel content of 0.11% or more had significant enfluence on corrosion resistant performance of weathering steels.
