The AOD uses a vessel that has a 3 step process in refining the stainless steel. These are Decarburization, Reduction, and Desulphurization. Decarburization simply means reducing the carbon content in the steel. Reduction is what is needed to prevent corrosion and Desulphurization is used to remove the sulfur dioxide. AOD was the brainchild of ...
