Abstract
In a plated steel sheet having an aluminum-plating layer comprising at least Al formed on one side or both sides of the steel sheet, there is provided a plated steel sheet which, owing to the presence of a surface coating layer containing a compound having wurtzite crystal structure on the aluminum-plating layer, has excellent lubricity, prevents the plating thickness from becoming uneven during heating, and can improve formability and productivity in hot stamping, and a method of hot-stamping the plated steel sheet.
