Improvement of Oxidation Behavior at 1,073 and 1,173K of Austenitic Stainless Steels by Addition of Ni

This work studied the effect of Nickel addition to improve the oxidation behavior of austenitic stainless steels at 1,073 K and 1,173 K. The results show that Nickel increases the oxidation resistance of the austenitic stainless steels. The compositions of oxide scale also change form only Cr2O3 to be Cr2O3, Fe2O3, NiFe2O4 and Ni (Cr2O4). The oxidation behavior follows the parabolic rate law; W = ktn, where W = weight gain (g/cm2), t = time (s), k is the exponential rate constant and n is the exponent of growth rate. The n values are between 0.47-0.88.
