The Atmospheric Corrosion of Carbon Steel and Cast Iron in the Environment of South Mosul

The carbon steel and cast iron are widely used metals in engineering and industrial applications. In this study, samples of carbon steel and cast iron chosen and distributed on six selected sites in the southregion of Mosul city in Iraq, Because these sites distinguished by the existence of natural emanations of hydrogen sulfide gas is produced and the existence of materials that cause metal corrosion like sulfates and chlorides. The corrosion measured by weight loss method according to the standard (ISO 9223:1992) and the higher rates registered in the sites that contain high emanations of hydrogen sulfide gas and sulfates and chlorides. In addition, it became obvious that there is a relationship between the corrosion exposure time and the corrosion rates which decreased by increasing of corrosion exposure time and continuous increasing in weight loss. The test continued for a complete year.
