Abstract:	The cyclic-oxidation behavior of a low-nickel austenitic stainless steel (LNiSS) at 873 and 973 K has been investigated up to 500 cycles. A wide range of experimental techniques, including SEM, EDS, and XRD have been applied to examine the oxide scales. After cyclic oxidation at 873 and 973 K, the new LNiSS alloy showed good oxidation resistance. XRD and EDS analysis show that composition of oxide scales developed during cyclic oxidation at 873 and 973 K are the same. The oxide scales formed a cubic oxide-type M₂O₃ and a cubic spinel-type M₃O₄ adhered well to the substrate.

Keywords:	low-nickel austenitic stainless steel high-temperature oxidation cyclic oxidation
