According to characteristics of high-strength weathering steel for railway use,variation of resistance to atmospheric corrosion of the steel was studied by adjusting the content of nickel. The results reveal that with low content of nickel and chromium,there are cracks existing between the base metal and the inner rusty scale. As the content of nickel rises,the rusty scale becomes thinner and more compact. At the initial stage of sun exposure,the rusty scale is mainly composed of γ-FeOOH,and along with the time extending,α-FeOOH gradually forms. Moreover,the higher nickel content,the higher α-FeOOH to γ-FeOOH ratio.
