PURPOSE:To produce easily a plated steel material having superior corrosion resistance and workability by electroplating a steel material with an Al alloy contg. a specified amount of Mn. CONSTITUTION:A steel material is electroplated with an Al alloy contg. 0.1-9wt%, preferably 1-5wt% Mn in a molten salt bath. The resulting Al alloy film has superior workability and satisfactory corrosion resistance. When the plated steel material is temper-rolled at about 0.1-0.5% draft, a fine glossy surface is obtd. without deteriorating the workability or corrosion resistance.
