The ferritic stainless steel having a good moldability, ridging property and corrosion resistance is produced by (a) casting a steel composed of at most 0.01wt.% C, at most 0.5 wt.% Si, at most 0.5 wt.% Mn, at most 0.02 wt.% P, at most 0.005 wt.% Si, 16-18 wt.% Cr, 0.3-0.6 wt.% Cu, 1.8-2.0 wt.% Mo, at most 0.02 wt.% N, (Nb+Ti) >= 8(C+N), 0.7 <= Nb/Ti <= 0.9, residual Fe and impurity, (b) heating the casted ingot at 1160-1200 deg.C, (c) hot rolling it at 830-870 deg.C, (d) not winding it at 680-720 deg.C, (e) continuously annealing it at 940-960 deg.C, and (f) cold rolling and cold annealing it at 940-960 deg.C.
