PROBLEM TO BE SOLVED: To provide a stainless steel sheet for an automobile fuel tank excellent in workability. SOLUTION: This stainless steel sheet for an automobile fuel tank is obtained by using an austenitic stainless steel sheet in which breaking elongation is >=50%, and work hardening ratio is <=4,000 N/mm2 when worked by uniaxial stretching or a ferritic stainless steel sheet in which breaking elongation is >=30%, and Lankford value (r value) is >=1.3 when worked by uniaxial stretching as base material and forming a resin film composed of a carboxyl group- containing urethane resin having an elastic modulus of 1,000 to 60,000 N/cm2 at 100 deg.C, in which solid lubricant grains are dispersed in the ratio of 1 to 35 mass% on the surface of the base material. In this way, the corrosion resistance of stainless steel is made the most of, and the volatilization of stored gasoline can be prevented over a long period. |
