Layered Blank For Hot Stamping And Layered Hot Stamp Molded Body

Abstract: [Problem] The present invention addresses the problem of ameliorating both low heating rate of a layered part and heating rate difference between the layered part and a single sheet part in cases where an Al plated steel sheet is used as a base material. [Solution] A layered blank for hot stamping according to the present invention is provided with: a first Al plated steel sheet which has a sheet thickness t1; and a second Al plated steel sheet which has a sheet thickness t2, and is superposed on and welded to the first Al plated steel sheet, while having a smaller area than the first Al plated steel sheet and having a carbon-based black coating film as an upper layer of an Al plating layer on a side that does not come into contact with the first Al plated steel sheet. This layered blank for hot stamping satisfies formula (1) to formula (5).
