A ferritic stainless steel sheet comprises: a predetermined chemical composition, wherein a difference between a maximum value and a minimum value of Vickers hardness in a thickness direction is HV 50 or less.

Ferritic stainless steel sheet and method of producing same

Provided is a hot-rolled and annealed ferritic stainless steel sheet excellent in surface quality after bending work has been performed. A hot-rolled and annealed ferritic stainless steel sheet has a thickness of 5.0 mm or more and a chemical composition containing, by mass %, C: 0.001% to 0.025%, Si: 0.05% to 0.70%, Mn: 0.05% to 0.50%, P: 0.050% or less, S: 0.01% or less, Cr: 10.0% to 18.0%, Ni: 0.01% to 1.00%, Al: 0.001% to 0.10%, N: 0.001% to 0.025%, Ti: 0.01% to 0.40%, and a balance of Fe and inevitable impurities, in which a difference between maximum and minimum values of an average crystal grain diameter determined by using measuring method 1 is 50 &#x3bc;m or less, and in which a difference between maximum and minimum values of a crystal grain elongation rate determined by using measuring method 2 is 5.0 or less.
