This study consists of three parts. Firstly the equivalently accelerative corrosive environment is determined through the analysis of statistic data of corrosion environment. Secondly the fatigue test is carried out under the constant amplitude cyclic loading for the specimens which are exposed in the corrosive environment for equivalent calendar time of zero year, 3 years, 8 years and 13 years. Four S-N curves with different corrosive time are obtained based on the fatigue experiment. Finally the regression method of S-N curves for experimental data is researched and a weighted least square fit is put forward in which the weigh of a group of test data is inversely proportional to the length of the confidence interval.
