Acid PipingSulphuric Acid
Carbon steel in the presence of strong sulphuric acid will corrode to form a thin film of iron sulphate on the surface of the metal. It is this film of corrosion product that once formed prevents further corrosion of the underlying material. However this protective film is very unstable an is easily disturbed and removed.

Corrosion behaviour of mild and high carbon steels in
Mild steel and high carbon steels are classified as fer-rous metals (they contain a large percentage of iron). Carbon steels are essentially iron-carbon alloys. They are sometimes subdivided by the broad range of carbon content which include (a) mild or low carbon steel (0.080.30 carbon) (b) medium carbon steel (0.30.5
