A high temperature corrosion resistant stainless steel having a composition (by weight) of: C ≤ 0.2%, but more than zero, N ≤ 0.1 % but more than zero, O ≤ 0.1 % but more than zero, Si ≤ 0.4% but more than zero, Al < 0.5% but more than zero, Mn ≤ 0.5% but more than zero, Cr 20 to 25%, Ni ≤ 2.0% but more than zero, Zr + Hf 0,01 to 0.1%, Ti ≤ 0.5% but more than zero, Mo + W ≤ 2.5% but more than zero, Nb + Ta ≤ 1.25% but more than zero, V ≤ 0.5% but more than zero, and balance of Fe and naturally occurring impurities and not more than 0.010% of S impurity. This steel is particularly suitable for the manufacturing of interconnects in solid oxide fuel cells. <IMAGE> |
