To obtain the corrosion behavior of 15CrMo exposed in saturated saline steam with Na₂SO₄ at the initial stage, the experiments are implemented in a novel setup. The results show corrosion products are mainly composed of FeOOH, Fe₂O₃ and Fe₃O₄. Compared with deionized steam, saline steam promotes the generation of FeOOH and Fe₂O₃. The generation of Fe₃O₄ is inhibited by salinity. The contents of FeOOH and Fe₂O₃ increase with temperature while that of Fe₃O₄ decreases. The contents of FeOOH and Fe₂O₃ decrease with time and that of Fe₃O₄ shows the reverse trend. The content of FeSO₄ keeps low all the time.

为了在初始阶段获得暴露于Na ₂ SO _4的饱和盐水蒸汽中的15CrMo的腐蚀行为，采用新颖的装置进行了实验。结果表明，腐蚀产物主要由FeOOH，Fe ₂ O ₃和Fe ₃ O _4组成。与去离子蒸汽相比，盐水蒸汽促进了FeOOH和Fe ₂ O _3的生成。盐度抑制了Fe ₃ O ₄的产生。FeOOH和Fe ₂ O ₃的含量随温度而增加，而Fe ₃ O ₄的含量随温度而增加减少。FeOOH和Fe ₂ O _3的含量随时间减少，而Fe ₃ O ₄的含量则呈相反的趋势。FeSO ₄的含量始终保持较低水平。
