| description | The present invention provides a ferritic stainless steel sheet for forming a raw material pipe for bellows pipe, in which both excellent formability and excellent high-temperature properties (high-temperature salt corrosion resistance and high-temperature fatigue properties) are obtained. Specifically, the ferritic stainless steel sheet for forming a raw material pipe for bellows pipe contains 0.015% by mass or less of C, 1.0% by mass or less of Si, 1.0% by mass or less of Mn, 0.04% by mass or less of P, 0.010% by mass or less of S, 11% to 19% by mass of Cr, 0.015% by mass or less of N, 0.15% by mass or less of Al, 1.25% to 2.5% by mass of Mo, 0.3% to 0.7% by mass of Nb, 0.0003% to 0.003% by mass of B, and the balance being Fe and incidental impurities. In the ferritic stainless steel sheet for forming a raw material pipe for bellows pipe, preferably, the average crystal grain diameter D of the steel sheet is 35 µm or less, and alternatively, the surface roughness Ra of the steel sheet is 0.40 µm or less. |
