    摘要: A ferritic stainless steel contains no expensive elements such as Mo and W, is free from the oxidation resistance loss caused by addition of Cu, and thereby has excellent levels of oxidation resistance (including water vapor oxidation resistance), thermal fatigue property, and high-temperature fatigue property. The ferritic stainless steel contains, in mass %, C at 0.015% or less, Si at 0.4 to 1.0%, Mn at 1.0% or less, P at 0.040% or less, S at 0.010% or less, Cr at 16 to 23%, Al at 0.2 to 1.0%, N at 0.015% or less, Cu at 1.0 to 2.5%, Nb at 0.3 to 0.65%, Ti at 0.5% or less, Mo at 0.1% or less, and W at 0.1% or less, the Si and the Al satisfying a relation Si (%)≧Al (%).
