The effect of copper on oxidation behavior of a C-Si-Mn steel was investigated. The samples were heated to 820°C and held for 75s under four different dew points with 5vol% hydrogen. The results of glow discharge optical emission spectrometry (GDOES), X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM) analysis techniques revealed the differences in oxidation. It is proposed that the steel containing 0.3 wt.% copper has less external oxidation of silicon and manganese compared to the steel containing no copper for all different dew points. As researched in this paper the external oxidation of C-Si-Mn steels would be suppressed by adding copper.
