The isothermal oxidation mass gain test is adopted to study the high-temperature oxidation behavior at 800 ℃ of 310S stainless steel prepared by selective laser melting （SLM） and cold rolling （CR）. The microstructure， oxidation kinetics， and oxide scale structure of SLM-310S and CR-310S are systematically analyzed. The results show that both SLM-310S and CR-310S exhibit a single-phase austenite structure. SLM-310S forms a fish-scale structure due to molten pool stacking， characterized by fine and uniform grains， each containing numerous columnar and cellular subgrains. In contrast， CR-310S has typical polygonal austenite grains containing numerous twins. During oxidation at 800 ℃， the mass gain of SLM-310S is lower than that of CR-310S， with oxidation rate constants of 5.612×10-4 mg2·cm-4·h-1 （SLM-310S） and 8.593×10-4 mg2·cm-4·h-1 （CR-310S）， respectively. Both specimens develop a double-layer oxide scale： the scale on SLM-310S is approximately 2-4 μm thick and mainly composes of SiO₂， Cr₂O₃ and MnCr₂O₄， while that on CR-310S additionally contains a small amount of Fe-containing oxides， along with pore defects within the matrix. Owing to its excellent microstructural characteristics， SLM-310S exhibits slower oxidation kinetics and a denser oxide scale， demonstrating superior high-temperature oxidation resistance at 800 ℃ compared to CR-310S.
