The research of corrosion behavior of T/P91 steel was investigated taking the case for the T/P91 steel corrosions existed during the construction process of a thermal power plant in Hunan province.The morphology change, product component and mechanical properties change were studied during the corrosion process of SO4-2. The results indicated that the surface oxide layer are mainly composed of iron and chromium oxide.As the thickness of oxide layer increased, the ability of blocking the erosive ions diffusion also come into effect, thus slow down the corrosion rate.
