The oxide scales of hot-rolled, annealed hot-rolled, and shot blasted annealed hot-rolled AISI 304L stainless steel with 0.2-0.4 wt.-%Cu and 1.0-1.7 wt.-%Mn were investigated by XRD. Mn but not Cu showed its effects on the oxide compounds. In the hot-rolled state, the oxide compounds consisted of Fe 2 O 3  and Cr 1.5 Mn 1.5 O 4  in all tested steels. Mn-rich (Fe,Mn) 2 SiO 4  was found in the oxide of the tested steel with 1.2 wt.-%Mn while Mn3O4 was found in the oxide of the tested steel with 1.7 wt.-%Mn. The addition of Mn promoted the formations of Cr 1.5 Mn 1.5 O 4 , Mn-rich (Fe,Mn) 2 SiO 4  and Mn 3 O 4 . The oxide compounds developed from Fe 2 O 3  to (Fe 0.6 Cr 0.4 ) 2 O 3  or Cr 1.3 Fe 0.7 O 3 , Cr 1.5 Mn 1.5 O 4  to CrMn 2 O 4  and Mn-rich (Fe,Mn) 2 SiO 4  to (Fe,Mn) 2 SiO 4  after the annealing process. The shot blasting process of annealed hot-rolled 304L stainless steel descaled the outer oxides as (Fe0.6Cr0.4)2O3 and (Fe,Mn) 2 SiO 4  and revealed the inner oxides Cr 1.3 Fe 0.7 O 3 , CrMn 2 O 4  and Cr 2 O 3 . The results clearly showed that the fraction of CrMn 2 O 4  increased according to the Mn content.
