ZMG TM 232G10 is an improved Fe-Cr ferritic alloy for SOFC interconnects which has better oxidation resistance than ZMG232L. Oxidation behavior of ZMG232G10 was investigated in air as well as H 2 /H 2 O atmosphere at 850 o C. ZMG232G10 showed almost same oxidation weight gain in both atmospheres. Oxidation behavior of some commercial Fe-Cr ferritic stainless steels was also investigated. 430 type stainless steel indicated a large amount of oxidation weight gain in air although it indicated a small amount of oxidation weight gain in H 2 /H 2 O. Oxide layers formed on the surface of ZMG232G10 were different from those of commercial stainless steels.
