초록

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-treatm...
