A composition change in oxide inclusions due to annealing in Si-Mn killed stainless steel was investigated. Using a confocal laser scanning microscope, SiO_2-MnO type oxides observed in bloom disappeared by annealing over 1273K. According to the thermodynamic calculation, SiO_2-MnO type oxides which are stable in molten steel temperature become unstable in annealing temperature and MnO-Cr_2O_3 type or SiO_2 type oxides become more stable. Also, a solubility of Cr_2O_3 in SiO_2-MnO liquid phase became very small in the annealing temperature. So, it would be possible that Cr_2O_3 containing MnO-SiO_2 type oxide becomes unstable and decomposed to MnO-Cr_2O_3 or SiO_2 type oxides by annealing treatment.
