Abstract: An automobile fuel container material and container has good workability, corrosion resistance of internal and external surfaces and weldability. Excellent environmental adaptability arises from the material being free from the elution of harmful components such as lead and chromium(VI). The automobile fuel container material includes a steel sheet, 5 to 80 g/m2 zinc plating as a first layer on at least one side of the surface of the steel sheet, 10 g/m2 nickel plating as a second layer, and not more than 5 g/m2 of a post-treatment layer. The post-treatment layer forms by coating partially reduced chromic acid and a reducing organic compound or can be an electrolytic chromate film as a lower layer and a resin as an upper layer.

Abstract: Disclosed are an automobile fuel container material and an automobile fuel container which have good workability, corrosion resistance of internal and external surfaces, and weldability, have excellent environmental adaptability, that is, are free from the elution of harmful components such as lead and chromium(VI), can be mass produced at low cost. The automobile fuel container material comprises: a steel sheet; a zinc plating as a first layer provided at a coverage of 5 to 80 g/m2 on at least one side of the surface of the steel sheet; a nickel plating as a second layer provided at a coverage of not more than 10 g/m2 on the zinc plating as the first layer; and a post-treatment layer as a third layer provided at a coverage of not more than 5 g/m2 on the nickel plating as the second layer.
