PROBLEM TO BE SOLVED: To provide a fuel tank and a fuel supply pipe that are made of stainless steel plate excellent in corrosion resistance, moldability and shock resistance and can keep crevice corrosion resistance for a long time in a severe corrosive atmosphere. SOLUTION: The stainless steel contains 0.015 mass% or less C, 0.5 mass% or less Si, 11.0-25.0 mass% or less of Cr, 0.020 mass% or less N, 0.05-0.50 mass% or less Ti, 0.10-0.50 mass% or less Nb, and 0.0100 mass% or less B, and further contains one or more of 3.0 mass% or less Mo, 2.0 mass% or less Ni, 2.0 mass% or less Cu, and 4.0 mass% or less Al if necessary. A ferritic stainless steel plate where breaking elongation is 30% or more when it is processed by one axis tension and r<SB>min</SB>value of Lankford value (r value) is 1.3 or more is used as a substrate. At least an overlapping section of the substrate ferritic stainless steel plate and the surface of a welding section are coated with zinc rich paint. COPYRIGHT: (C)2005,JPO&NCIPI
