<p>PURPOSE: A titanium-containing ferritic stainless steel with superior ridging resistance and a manufacturing method thereof are provided to reduce the size of grains and ridging by controlling annealing temperatures and to shorten the polishing time of end products. CONSTITUTION: Titanium-containing ferritic stainless steel with superior ridging resistance comprises C of 0.05 weight% or less(except 0), Si of 1.0 weight% or less(except 0), Mn of 1.0 weight% or less(except 0), P of 0.050 weight% or less(except 0), S of 0.020 weight% or less(except 0), Ni of 2.0 weight% or less(except 0), Cr of 15.0-25 weight%, Cu of 1.0 weight% or less, Nb of 0.1-0.5 weight%, Ti of 0.01-0.3 weight%, Al of 0.10 weight% or less(except 0), N of 0.05 weight% or less(except 0), one or more selected from Mo of 1.0 weight% or less(except 0), V of 0.01-0.30 weight%, Zr of 0.01-0.30 weight%, and B of 0.0010-0.0100 weight%, and Fe and inevitable impurities of the remaining amount.</p> |
