Abstract

The present invention provides: a ferrite stainless hot-rolled-and-annealed steel sheet that is excellent for punching, has substantial corrosion resistance, and makes it possible to achieve a prescribed dimensional precision without cracking when punched into a thick flange; and a production method for the ferrite stainless hot-rolled-and-annealed steel sheet. A ferrite stainless hot-rolled-and-annealed steel sheet that has a ferrite single phase structure that has a component composition that contains, by mass%, 0.001%-0.020% of C, 0.05%-1.00% of Si, 0.05%-1.00% of Mn, no more than 0.04% of P, no more than 0.01% of S, 0.01%-0.10% of Al, 10.0%-20.0% of Cr, 0.50%-2.00% of Ni, 0.10%-0.40% of Ti, and 0.001%-0.020% of N, the remainder being Fe and unavoidable impurities, the average crystal grain size of the metal structure of the ferrite single phase structure being 5-20 µm.
