    摘要: A metal material for an inter-connector of a solid oxide type fuel cell which has a chemical composition, in mass %: C: 0.20 % or less, Si: 0.02 to 1.0 %, Mn: 2.0 % or less, Cr: 10 to 40 %, Mo: 0.03 to 5.0 %, Nb: 0.1 to 3.0 %, provided that 0.1 ≤ Mo/Nb ≤ 30, one or more selected from among Sc, Y, La, Ce, Pr, Nd, Pm, Sm, Zr and Hf: 1.0 % in total, and the balance: Fe and inevitable impurities. The metal material is excellent in the resistance to oxidation, is improved in the resistance to exfoliation of an oxidized film due to the reduced growing rate of the oxidized film, has good electroconductivity, exhibits a reduced difference in thermal expansion between it and a suitable electrolyte, and can be produced at a low cost.
