<p>A ferritic stainless steel plate, characterized as comprising, in mass %, 0.02 to 0.06 % of C, 1.0 % or less of Si, 1.0 % or less of Mn, 0.05 % or less of P, 0.01 % or less of S, 0.005 % or less of Al, 0.005 % or less of Ti, 11 to 30 % of Cr, 0.7 % or less of Ni, and also N in an amount satisfying the formulae: 0.06 ≤ (C+N) ≤ 0.12 and 1 ≤ N/C, and further V in an amount satisfying the formula: 1.5 X 10-3 ≤ (V x N) ≤ 1.5 X 10-2, wherein C, N and V represent the contents (mass %) of respective alloy elements. The ferritic stainless steel plate exhibits good formability and excellent surface quality after forming.</p> |
