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 3):
The hot-stamped member according to  claim 1 ,\n wherein, in the tailored blank for hot stamping, an Ac 1  point of the weld metal defined in unit \u00b0 C. in the following formula (3) is 860\u00b0 C. or lower,\n Ac 1 =exp(6.5792\u22120.038058\u00d7C+0.052317\u00d7Si+0.011872\u00d7Ni\u22120.045575\u00d7V+0.18057\u00d7Al+0.011442\u00d7W\u22120.013403\u00d7Cu+5.5207\u00d7B+0.91209\u00d7S\u22121.1002\u00d7P+0.060014\u00d7Mn\u00d7C\u22120.096628Cr\u00d7C+0.050625\u00d7Cr\u00d7Si+0.39802\u00d7Mo\u00d7C\u22120.34782\u00d7Mo\u00d7Mn+0.40986\u00d7Mo\u00d7Si\u22120.12959\u00d7Mo\u00d7Cr\u22120.048128\u00d7Ni\u00d7C\u22120.01090\u00d7Mn 2 \u22120.03550\u00d7Si 2 +0.010207\u00d7Cr 2 +0.36074\u00d7Mo 2 \u22120.0030705\u00d7Ni 2 )\u2003\u2003Formula (3) \n where, C, Si, Ni, V, Al, W, Cu, B, S, P, Mn, Cr, and Mo in Formula (3) represent amounts, in mass %, of individual elements in the weld metal, and elements not contained are considered to have an amount of zero in computation.
