AUTOMOBILE FUEL CONTAINER MATERIAL EXCELLENT IN ENVIRONMENT COMPATIBILITY AND AUTOMOBILE FUEL CONTAINER

摘要

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. The post-treatment layer has been formed by coating using partially reduced chromic acid and a reducing organic compound as essential components or comprises an electrolytic chromate film as a lower layer and a resin as an upper layer.
