Aluminum Plated Steel Sheet For Hot Stamping

Abstract: This aluminum-plated steel sheet for hot stamping comprises a base steel sheet, an aluminum plating layer that is provided on at least one surface of the base steel sheet, and a surface treatment film that is provided on the aluminum plating layer; the surface treatment film contains a compound A that contains carbon and a compound B that is an oxide or fluoride of a metal element M and has a rutile structure; the carbon concentration of the compound A is 80% by mass or more; and the concentration of the metal element M satisfies formula (1) and formula (2). (1): 1 = CbM = 40 (2): 1.5 = CbM/CtM = 10.0 If H (µm) is the average thickness of the surface treatment film, CtM in formula (2) is the concentration, in mass%, of the metal element M at a position of 0.05H from the surface of the surface treatment film, and CbM in formula (1) and formula (2) is the concentration, in mass%, of the metal element M at a position of 0.95H from the surface of the surface treatment film.
