Provided is ferritic stainless steel that realizes high corrosion resistance of a welded zone and that has high resistance to weld cracking. The ferritic stainless steel contains, by mass%, C: 0.001% to 0.030%, Si: 0.03% to 0.80%, Mn: 0.05% to 0.50%, P: 0.03% or less, S: 0.01% or less, Cr: 19.0% to 28.0%, Ni: 0.01% to less than 0.30%, Mo: 0.2% to 3.0%, Al: more than 0.15% to 1.2%, V: 0.02% to 0.50%, Cu: less than 0.1%, Ti: 0.05% to 0.50%, N: 0.001% to 0.030%, and Nb: less than 0.05%. Expression (1) is satisfied and the balance is Fe and inevitable impurities. Nb × P ‰¤ 0.0005 In Expression (1), each element symbol represents the content (by mass%) of the element. |
