Mild steel due to its versatile properties like strength, ductility is mostly used in various fields like construction, transport and industrial components. Mild steel is prone to atmospheric corrosion; especially in marine atmosphere, corrosion is more pronounced. The focus of the present work is to know the behavior of the metal and corrosion product upon exposure to 3% Sodium chloride solution. Dissolution pattern of these components along with the fresh steel was analyzed. Macroscopic observation of the dissolution pattern reveals most interesting features like bubble formation and collapse of bubble and crystallization of sodium chloride in the nests. Various types of changes occurring during this dissolution process were recorded. XRD analysis of corrosion product so obtained in short time exposure to aggressive environments was done. SEM images taken after the drying stage resembled the same patterns as macro corrosion.
