The effects of acid rain and salt content on corrosion behavior were investigated with rolling stock structural steels be caused by environmental. Since these materials are exposed to the corrosive environments like polluted air, acid rain and sea water, it is important to investigate corrosion behaviour in various corrosive environments. The aqueous corrosion of the characteristic materials in aerated acid rain and neutral solution were studied by using immersion tests, electrochemical measurements and analytical techniques. In order to examine corrosion characteristic, structural steels were electrochemically evaluated with respect to the dissolved oxygen content, pH, chloride ion concentration.
