초록

The STS304 stainless steel was oxidized isothermally and cyclically at temperatures between 1050 and $1200^{\circ}C$ for 1 hr in air. During isothermal oxidation, it displayed good oxidation resistance at $1050^{\circ}C$. However, it suffered from breakaway oxidation above $1100^{\circ}C$, being accompanied with internal oxidation. During cyclic oxidation, it also displayed good oxidation resistance at $1050^{\circ}C$, but it suffered from massive weight loss above $1125^{\circ}C$. The oxide scales formed consisted primarily of $Fe_2O_3$, $Fe_3O_4$ with and without $Cr_2O_3$. They were generally non-adherent.
