Abstract
During the production of magnesium and its alloys, the melt is in contact with steel at various stages of the process. Steel can be eroded and corroded through chemical reactions with molten magnesium and the protective gases such as SF6 or SO2. The dissolution rate and corrosion mechanism of steels in molten magnesium were investigated by the rotating cylinder method. The corrosion behavior of four steel grades, i.e. high carbon and low carbon steel, stainless steel 316 and 400 were examined for AZ31 melt under N2-l% SF6 gas atmosphere. The corrosion rates were found to be different depending on steel grades. It is found that the corrosion mechanism of steels in magnesium melts involves a two-stage process consisting of oxidation of Fe and its reduction by magnesium melt.
