PROBLEM TO BE SOLVED: To produce ferritic stainless steel having excellent high-temperature strength, high-temperature oxidation resistance and high-temperature salt damage resistance and capable of withstanding use at high temperatures exceeding 900°C. SOLUTION: Material components are regulated to a composition range consisting of, by mass,≤0.02% C, 0.5 to 2.0% Si,≤2.0% Mn, 12.0 to 16.0% Cr, 1.0 to 5.0% Mo, >2.0 to 5.0% W, 5(C+N) to 1.0% Nb,≤0.02% N and the balance Fe with inevitable impurities.
