Some corrosive agents for ferrous alloys
WebThe most common ferrous alloys used in automobiles are cast iron, mild steel, carbon steel and stainless steel. Corrosion of ferrous metals is normally occurred by oxidation of iron … WebThe major atmospheric corrosive agents are oxygen and airborne moisture, both of which are in abundant supply. Corrosion often results from the direct action of atmospheric oxygen and moisture on metal, and the presence of additional moisture often accelerates corrosive attack, particularly on ferrous alloys.
