The oxidation behaviour of Low alloy steel its German designation (20mnmoni55) and AISI 304 steel has been studied in air under cyclic conditions at 900°C for 50 hr cyclic. Oxidation kinetics was established by thermogravimetric technique. Each cycle consisted of 1 hour heating at 900°C followed by 20 min of cooling in air. Low alloy steel sample followed somewhat linear rate of oxidation with more weight gain while AISI 304 sample followed the non-linear rate law of oxidation with less weight gain. The microstructural feature and phase transformation of oxide scales were characterise by X-ray diffraction (XRD) and field emission scanning electron microscopy/energy dispersive X-ray (FESEM/EDAX) techniques.
