The present invention provides for a ferritic stainless steel having excellent brazeability in the case where brazing is conducted at high temperatures under low oxygen partial pressures. This ferritic stainless steel includes, in terms of mass percent, 0.03% or less of C, 0.05% or less of N, 0.015% or more of C + N, 0.1 to 1.5% of Si, 0.02 to 2% of Mn, 15 to 22% of Cr, 0.03 to 1% of Nb, 0.002 to 0.1% of Al, 0.002 to 0.004% of Ti, and 0.01% or less of S, with the remainder composed of Fe and unavoidable impurities, wherein the chemical composition satisfies the following formulae (1) and (2): Ti - 3N <= 0.004 ...(1) 10(Ti - 3N) + Al <= 0.14 ...(2). The atomic symbols in formulae (1) and (2) indicate the content (mass %) of the respective element, and the numerical values that precede the atomic symbols are constants. |
