Abstract (en)
[origin: EP1413640A1] Ferritic stainless steel has a chemical composition, in mass %: C: 0.03% or less, Si: 1.0% or less, Mn: 1.5% or less, Ni: 0.6% or less, Cr: 10 to 20%, Nb: 0.50% or less, Cu: 0.8 to 2.0%, Al: 0.03% or less, V: 0.03 to 0.20%, N: 0.03% or less, provided that Nb is greater than or equals 8(C+N) is satisfied, and balance: Fe and inevitable impurities. The Mo content of the ferritic stainless steel as an impurity is preferably controlled to 0.10 mass% or less, and Ti and B may be optionally contained in amounts of 0.05 to 0.30 and 0.0005 to 0.02 mass%, respectively.
