摘要：
The present invention relates to aluminum plated steel sheet which does not require coating after plating and is high in production flexibility enabling application of conventional production processes as they are or exhibits excellent corrosion resistance to flex fuels and further is excellent in appearance and to fuel tanks characterized by being produced using the steel sheet. The Si, Mg, Ca, and Ti ingredients in the aluminum plating layer are defined and the cooling method after hot dip aluminum coating is controlled to make Mg2Si particles with a long axis of 10 μm or less and an aspect ratio of 1 to 3 finely disperse in the plating layer. Due to the Mg2Si particles, it is possible to give an excellent corrosion resistance to flex fuels and suppress the deterioration in appearance due to MgO.
