Metallic oxide layer of heat resistant element contributes to the high-temperature oxidation resistance by delaying the oxidation, and also has positive effect on the electrical resistivity increase. In this study, the green compacts of Fe-Cr-Al powder mixed with STS434L were oxidized at 950°C up to 210 hrs in order to consider the effect of metal oxide on the oxidation and electrical resistance. It exhibited the low oxidation resistance in case of 434L only, however it increased as the amount of Fe-Cr-Al powder in the 434L compact. The higher electrical resistivity was observed at the Fe-Cr-Al compact with and 434L powder. The metal oxides of (Fe_0.6C_0.4)₂O₃, Cr₂O₃, and Fe₂O₃ contributed to the electrical resistivity, whereas Al₂O₂ took a role of oxidation resistance.
