Abstract (en)
Ferritic stainless steel having a high degree of ductility and a method for manufacturing the ferritic stainless steel are provided. The stainless steel according to one aspect of an embodiment of the present invention includes, by wt%, C: 0.005% to 0.1%, Si: 0.01 % to 2.0%, Mn: 0.01 % to 1.5%, P: 0.05% or less, S: 0.005% or less, Cr: 10% to 30%, Ti: 0.005% to 0.5%, Al: 0.01 % to 0.15%, N: 0.005% to 0.03%, and the balance of Fe and inevitable impurities, wherein the ferritic stainless steel includes 3.5 x 106 or fewer particles of an independent Ti(CN) precipitate per square millimeter (mm2) of ferrite matrix.
