Abstract (en)
[origin: EP3878993A1] This ferritic stainless steel sheet contains Cr: 11.0% or more and 25.0% or less, C: 0.001 % or more and 0.010% or less, Si: 0.01% or more and 1.0% or less, Mn: 0.01 % or more and 1.0% or less, P: 0.10% or less, S: 0.01% or less, and N: 0.002% or more and 0.020% or less, and either one or both of Ti: 1.0% or less and Nb: 1.0% or less, with a remainder of Fe and impurities. The ferritic stainless steel sheet has a ferrite single-phase microstructure in which the grain size number is larger than 9.0, and the random intensity ratios of crystal orientations in planes parallel to a rolled surface at a sheet thickness 1/2 position and a sheet thickness 1/10 position are I<sub>{554}<225></sub> ≥ 7.0, I<sub>{411}<148></sub> ≥ 0.9, and I<sub>{211}<011></sub> ≥ 1.0.
