General works Metals Chemicals Mild steel is a type of carbon steel with quite a low carbon content, or particularly known as plain- carbon steel. It is often used as a construction material because of its relatively low price.

The complexes showed better effectiveness in hydrochloric acid (HCl) rather than sulphuric acid (H2SO4) solution. The corrosion happened more actively in HCl than H2SO4 due to the chloride ions showing more destructive effect than sulfate ion on the carburized low carbon steel samples.
