Provided is a ferritic steel that is particularly creep-resistant at temperatures from 600 to 1000° C. The ferritic steel comprising precipitations of an intermetallic phase of the Fe2(M, Si)-type or Fe7(M, Si)s-type, wherein M is a metal, particularly niobium, molybdenum, tungsten and/or tantalum. The precipitations being formed at high temperatures. The alloy can additionally comprise chromium. The steel can be used, among other things, for the bipolar plate in a stack of high-temperature fuel cells. |
