'''Argon oxygen decarburization''' ('''AOD''') is a process primarily used in [[stainless steel]] [[steel making|making]] 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 (chemistry)|reduction]], and [[desulphurization]]. AOD was invented in 1954 by the Lindé Division of The Union Carbide Corporation <ref>{{cite journal|title=The linde argon-oxygen process for stainless steel; A case study of major innovation in a basic industry|journal=Metallurgical Transactions|year=1973|volume= 4|issue =6|pages=1439–1447|author=Krivsky, W.
