Abstract
High-temperature oxidation of duplex stainless steels S32101 and S32304 was performed under three conditions: isothermal oxidation at 1050 °C in air and simulated industrial reheating atmosphere and in situ oxidation in air during the continuous heating to 1050 °C. Breakaway oxidation was found in S32101 but not in S32304, before which the weight gain per unit area was in parabolic relation to time. A triplex oxide layer of S32101 and a duplex-layer of S32304 oxidized for 120 min were observed, respectively. The initial oxidation phase was austenite for S32101 and ferrite for S32304 due to different manganese content.
