<p>The present invention relates to a ferritic stainless steel sheet with a superior anti-ridging property and a method of manufacturing the same, capable of improving a ridging property by controlling a reduction ratio in cold rolling. According to an embodiment of the present invention, in the method of manufacturing a ferritic stainless steel with a superior anti-ridging property according to the embodiment of the present invention, a slab containing 0.0005-0.01 wt% of C, 0.005-0.015 wt% of N, 0.01-0.20 wt% of Si, 0.01-0.20 wt% of Mn, 0.001-0.03 wt% of P, 0.0001-0.005 wt% of S, 15.0-17.0 wt% of Cr, 0.01-0.20 wt% of Ni, 0.001-0.10 wt% of Al, 0.10- 0.30 wt% of Ti, 0.01- 0.10 wt% of Nb, and the remainder consisting of Fe and other inevitable impurities, is prepared. Hot rolling, annealing, and cold rolling are performed on the slab. In the cold rolling process, primary cold rolling is performed at a reduction ratio of 25% or more, and secondary cold rolling is performed at a reduction ratio of 78% or more. After each of the primary and secondary cold rolling, annealing is performed. An annealing temperature after the secondary cold rolling has been performed is controlled to be in the range of 850°C to 950°C.</p> |
