Abstract

Stainless steel that has excellent oxidation resistance, resistance to Cr poisoning, and electrical conductivity not only in the operating environments of SOFCs but also in the operating environments of SOECs. The chemical composition is appropriately controlled, in particular, to Al: 0.60 mass% to 1.50 mass%, Nb: 0.20 mass% to 0.45 mass%, Cr: 20.0 mass% to 30.0 mass%, and Si: 0.05 mass% to 0.50 mass%, and the relationships of the following expressions (1) and (2) are satisfied: 0.03 × [Cr] + [Al] ≤ 2.20 ...(1), 0.44 × [Si] + [Al] ≤ 1.52 ...(2).
