Abstract

This work focuses on the effect of alloyed sulphur as MnS inclusions in austenitic stainless steels. AISI 304L and AISI 303 were oxidized at 1000 °C in synthetic air. The high sulphur grade, AISI 303, presents a breakaway oxidation with formation of nodules with an inner part composed of alternated layers of Fe-rich and Cr-rich oxides. During oxidation, MnS inclusions near the metal/oxide interface are partially dissociated. Manganese is incorporated in the oxide. The sulphur is trapped in Cr,Mn-oxysulphide aggregates which formation leads to a local decrease of the Cr concentration and consequently to the formation of non-protective Fe-rich oxide.
