To make oxidation behavior of stainless steel clear, an in-depth scale structure characterization method for multilayered scale formed on stainless steel using both Raman spectroscopy and Glow discharge optical emission spectroscopy (GDS) was developed. In this work, cold rolled Type 304 stainless steels containing 1.0 mass% Mn and 1.5 mass% Mn annealed at the temperature range from 1050℃ to 1150℃ were prepared to investigate glowth mechanism of thin oxide layers of which thicknesses are about 100 nm. Each thickness of spinel structure layer and corundum structure was estimated by GDS on the basis of proposed thickness estimation model. The main results obtained are as follows : (1) The glowth rate of corundum structure layer was highly dependent on the annealing temperature than that of spinel, (2) the glowth rate of spinel structre layer formed on 1.5 mass% Mn stainless steel was higher than that formed on 1.0 mass% Mn stainless steel, (3) the growth rate of corundum structure layer formed on 1.0 mass% Mn stainless steel was higher than that formed on 1.5 mass% Mn stainless steel, (4) the glowth rate of corundun structure layer formed on 1.5 mass% Mn was highly dependent on the annealing temperature than that formed on 1.0 mass% Mn stainless steel.
