Abstract (en)
[origin: EP3438310A1] Provided is a ferritic stainless steel sheet that has low susceptibility to exfoliation of black spots on a weld bead (in a TIG weld zone, in particular) during bending. The ferritic stainless steel includes, in mass%, C: 0.020% or less, Si: 0.05 to 0.50%, Mn: 0.05 to 0.50%, P: 0.040% or less, S: 0.030% or less, Al: 0.001 to 0.150%, Cr: 18.0 to 25.0%, Ti: 0.01 to 0.50%, Ca: 0.0001 to 0.0015%, O (oxygen): 0.0015 to 0.0040%, and N: 0.025% or less, with the balance being Fe and incidental impurities. The ferritic stainless steel sheet further satisfies formula (1), below: 0.5 ‰¤ PBI ‰¤ 20.0 ...(1) (where PBI = (7Al + 2Ti + Si + 10Zr + 130Ca) × O (oxygen) × 1000, and Al, Ti, Si, Zr, Ca, and O (oxygen) in the formula each represent a content [mass%] of a corresponding element in the ferritic stainless steel sheet, and the content of an element not included in the ferritic stainless steel sheet is 0).
