Abstract (en)
[origin: EP2264202A1] A ferritic stainless steel being excellent in thermal fatigue resistance and oxidation resistance and also having toughness that is equivalent to or higher than that of Type 429 is provided without adding an expensive element such as Mo or W. Specifically, the ferritic stainless steel includes C: 0.015 mass% or less, Si: 0.5 mass% or less, Mn: 0.5 mass% or less, P: 0.04 mass% or less, S: 0.006 mass% or less, Cr: 16 to 20 mass%, N: 0.015 mass% or less, Nb: 0.3 to 0.55 mass%, Ti: 0.01 mass% or less, Mo: 0.1 mass% or less, W: 0.1 mass% or less, Cu: 1.0 to 2.5 mass%, Al: 0.2 to 1.2 mass%, and the balance of Fe and inevitable impurities.
