The AOD process features the use of mixed gas (O 2 + inert gas) top-blowing lances to achieve high decarburization rates even at low steel bath [C] contents. The AOD (argon-oxygen decarburization) is a bottom-blown process, which since its introduction in the late 1960’s has become the dominant stainless steelmaking
