Steel sheet plated with Al—Fe for hot press forming having excellent corrosion resistance and spot weldability, and manufacturing method thereof

An aluminum-iron-based plated steel sheet for hot press forming, the aluminum-iron-based plated steel sheet comprising:

• a base steel sheet;
• and
• a plated layer formed on a surface of the base steel sheet,
• wherein the plated layer comprises:
• an alloying layer formed on the surface of the base steel sheet and containing at least one of Fe3Al, FeAl(Si), Fe2Al5, and FeAl3;
• and
• an aluminum layer formed on the alloying layer and having a thickness less than 10% of a thickness of the plated layer, and
• wherein the plated layer has a thickness of 20 to 35 μm and contains 1 to 20 weight % of magnesium (Mg), measured by a glow discharge spectrometer (GDS) at a position 0.1 μm deep from a surface of the plated layer, and 10 weight % or less of oxygen measured by the GDS at the position 0.1 μm deep from the surface of the plated layer.
