<p>The present invention relates to a ferritic stainless steel sheet having superior ridging resistance and a method of manufacturing the same, capable of improving the ridging properties of a ferritic stainless steel sheet by controlling contents of carbon and nitrogen to be lowered. According to a method of manufacturing a ferritic stainless steel sheet having superior ridging resistance, a slab containing 0.0005-0.03 wt% of C, 0.010-0.03 wt% of N, 0.01-0.50 wt% of Si, 0.01-0.20 wt% of Mn, 0.01-0.70 wt% of Mn, 0.001-0.035 wt% of P, 0.0001-0.005 wt% of S, 15.0-17.0 wt% of Cr, 0.001-0.50 wt% of Ni, and the remaining amount of Fe and inevitable impurities is prepared in which the sum of contents of C and N is 0.04 wt% or less. The slab is subject to hot rolling, primarily annealing, cold rolling, and secondary annealing. In an internal structure of the slab, the maximum austenite phase amount (γmax) is less than 10% and the transformation temperature (Acl) of austenite is 850°C or more.</p> |
