Ferritic stainless steel sheet

Abstract

Provided is a ferritic stainless steel sheet excellent in terms of corrosion resistance with which a decrease in the quantity of surface defects and an improvement in toughness are realized at the same time. The ferritic stainless steel sheet has a chemical composition containing, by mass %, C: 0.020% or less, Si: 0.05% to 0.40%, Mn: 0.05% to 1.00%, P: 0.040% or less, S: 0.030% or less, Al: 0.001% to 0.15%, Cr: 20.0% to 23.0%, Ni: 0.01% to 0.80%, Cu: 0.30% to 0.80%, Ti: 0.10% to 0.50%, Nb: 0.010% to 0.150%, Zr: 0.005% to 0.150%, N: 0.020% or less, and the balance being Fe and inevitable impurities, in which relational expression (1) below is satisfied. Zr≤Nb≤Ti  (1) (Here, each of Zr, Nb, and Ti in relational expression (1) denotes the content (mass %) of the corresponding chemical element.)
