Abstract Corrosion behavior of 19 low alloy steels with different compositions under different atmospheric conditions is reported in this paper. The time of exposure extends as long as 15 years at 10 experimental sites typical of diferent atmospheres. The results show that corrosion behavior of steels varies remarkably with atmospheric conditions. Alloying elements such as Cu, Ti, Re, Mn are beneficial to the improvement of atmospheric corrosion resistance, with Cu being the most effective. Rust layers are investigated by means of X-ray diffractometer, SEM, EPMA aswell as electrochemical techniques. Regression equation expressing the relation between weight loss and time has been derived from short-term experimental data through statstical treatment,and is used for finite extrapolation forecast. It is observed that the corrosion resistance of the low alloyed Mn steel placed at the site of a river bridge is inferior to that of carbon steel on extended exposure.
