摘要

One form of this ferritic stainless steel sheet is a ferritic stainless steel sheet which contains 0.03% or less of C, 0.05% or less of N, 1% or less of Si, 1.2% or less of Mn, 14% (C + N) or more and 0.8% or less and Al: 0.1% or less, the balance being Fe and inevitable impurities, and a film satisfying the formula (1) is formed on the surface. d _f x Cr _f + 5 (Si _f + 3 Al _f ) (Equation 1) d _f represents the thickness (nm) of the film, Cr _f represents the Cr cation fraction in the film, Si _f represents the Si cation fraction in the film, and Al _f represents the Al cation fraction in the film.
