Argon oxygen decarburization (AOD) is a process primarily used in stainless steel making (secondary steelmaking) and other high grade alloys with oxidizable elements such as chromium and aluminum. After initial melting the metal is then transferred to an AOD vessel where it will be subjected to three steps of refining; decarburization, reduction, and desulfurization.[1] (which became known as Praxair in 1992).[2]
