Disclosed is steel for a solid oxide fuel cell, which has excellent oxidation resistance, good electrical conductivity and a thermal expansion coefficient similar to that of a ceramic component such as an electrolyte or an electrode by achieving a remarkable improvement of the oxidation resistance and a reduction in the evaporation amount of Cr. Specifically disclosed is steel for a solid oxide fuel cell, which has excellent oxidation resistance and contains, in mass%, 0.1% or less of C, 0.2% or less of Al, 0.2% or less of Si, 0.4% or less of Mn, 16.0-28.0% of Cr, 1.5% or less of Ni, 1.0% or less of REM and/or Zr in total, 1.0-3.0% of W, and more than 0.2% but 4.0% or less of Cu, with the balance made up of Fe and unavoidable impurities. |
