FeCr model alloys with variation of chromium content, reactive element addition and spinel forming elements were studied in respect to oxidation resistance at 800°C. Additionally, in-situ studies were carried out to characterize the high temperature conductivity of the formed surface oxide scales. Based on these results, two model steels and a commercial material, alloy 446, were selected tor further qualification. First tests in respect to oxide scale formation, oxide conductivity, formation of volatile species and compatibility with contact materials showed potential suitability of these steels as construction material for SOFC interconnect.
