Abstract:
A tailored blank for hot stamping includes a welded portion formed by butt-welding a first aluminum-plated steel sheet and a second aluminum-plated steel sheet, an Average Al concentration of a weld metal in the welded portion is in a range of 0.3 mass % to 1.5 mass %, an Ac 3  point of the weld metal is 1250° C. or lower, and furthermore, an aluminum layer formed during the butt-welding is present on a surface of the welded portion.

Claim (Index 1):
A hot-stamped member obtained by performing hot stamping on a tailored blank for hot stamping,\n wherein a product of a hardness of the weld metal and a thickness of a thinnest portion of the weld metal is greater than both a product of a hardness of the first aluminum-plated steel sheet and a sheet thickness of the first aluminum-plated steel sheet and a product of a hardness of the second aluminum-plated steel sheet and a sheet thickness of the second aluminum-plated steel sheet, and wherein the tailored blank for hot stamping includes\n a welded portion formed by butt-welding the first aluminum-plated steel sheet and the second aluminum-plated steel sheet, \n wherein an average Al concentration of the weld metal in the welded portion is 0.3 mass % to 1.5 mass %, in the following formula (1), an Ac 3  point of the weld metal defined in unit OC is 1250\u00b0 C. or lower, and wherein an aluminum layer formed during the butt-welding is present on a surface of the welded portion,\n Ac 3 =910\u2212230\u00d7C 0.5 \u221215. 2\u00d7Ni+44. 7\u00d7Si+104\u00d7V+31. 5\u00d7Mo+13. 1\u00d7W\u221230\u00d7Mn\u221211\u00d7Cr\u221220\u00d7Cu+700\u00d7P+400\u00d7Al+120\u00d7As+400\u00d7Ti\u2003\u2003Formula(1) \n where, C, Ni, Si, V, Mo, W, Mn, Cr, Cu, P, Al, As, and Ti in Formula (1) represent amounts of individual elements in the weld metal in mass %, and elements not contained are considered to have an amount of zero in computation.
