摘要：
Ferritic stainless steel is excellent in terms of both oxidation resistance and thermal fatigue resistance without adding expensive elements, such as Mo or W. The ferritic stainless steel, contains: 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.
