SURFACE-TREATED STEEL PLATE, FUEL PIPE, CELL CAN

摘要

Provided is a surface-treated steel plate obtained by forming an iron-nickel alloy layer on the topmost surface, the surface-treated steel plate being characterized in that the Fe/Ni value obtained by Auger electron spectroscopy on the surface of the iron/nickel alloy layer is in the range of 0.3-2.0. In accordance with the present invention, there is provided a surface-treated steel plate having excellent corrosion resistance and in which the occurrence of pitting is effectively reduced when the surface-treated steel plate is exposed to various fuels such as automotive fuel oil.
