Summary:PURPOSE:To produce austenitic stainless steel for a solid electrolyte type fuel cell showing excellent oxidation resistance and electrical conductivity even in a high temp. oxidizing atmosphere. CONSTITUTION:The componental constitution of austenitic stainless steel is formed of a one contg. <=0.1% C, 0.5 to 3.0% Sr, <=3.00% Mn, 15 to 30% Cr, 20 to 60% Ni and 2.5 to 5.5% Al or furthermore contg. one or >= two kinds among one or more kinds among Ti, Nb and Zr by 4X[C(%)+N(%)] to 1.0%, <=1.0% of one or more kinds among Y, rare earth elements and Ca and <=10.0% Mo, and the balance Fe with inevitable impurities.
