Beschreibung
Zusammenfassung:	This ferritic stainless steel sheet is characterized by being composed of, in mass%, 0.02% or less of C, 0.15% or less of Si, 0.3-1% of Mn, 0.04% or less of P, 0.003% or less of S, 20-25% of Cr, 0.5-2% of Mo, 0.1% or less of Al, 0.02% or less of N, 0.001-0.5% of Nb, and the balance made up of Fe and unavoidable impurities. This ferritic stainless steel sheet is also characterized by satisfying formula (1). 2.5 < Mn/(Si+Al) < 8.0 (1) In formula (1), Mn, Si and Al represent the contents (mass%) of the respective elements.
