<p>This invention provides a ferritic stainless steel excellent in terms of both oxidation resistance and thermal fatigue resistance without adding expensive elements, such as Mo or W. Specifically, this invention provides a ferritic stainless steel, containing: C: 0.015 mass% or lower, Si: 1.0 mass% or lower, Mn: 1.0 mass% or lower, P: 0.04 mass% or lower, S: 0.010 mass% or lower, Cr: 16 to 23 mass% or lower, N: 0.015 mass% or lower, Nb: 0.3 to 0.65 mass%, Ti: 0.15 mass% or lower, Mo: 0.1 mass% or lower, W: 0.1 mass% or lower, Cu: 1.0 to 2.5 mass%, Al: 0.2 to 1.5 mass%, and the balance of Fe and inevitable impurities.</p> |
