AL-PLATED STEEL SHEET FOR HOT PRESSING AND PROCESS FOR MANUFACTURING AL-PLATED STEEL SHEET FOR HOT PRESSING.

摘要

[Problem] To provide an Al-plated steel sheet which is to be subjected to hot pressing and which exhibits excellent hot lubricity, excellent corrosion resistance after coating and excellent spot weldability. [Solution] This Al-plated steel sheet for hot pressing comprises a steel sheet, an Al deposit layer formed on one or both surfaces of the steel sheet, and a surface film layer formed on the Al deposit layer, wherein: the surface film layer contains a zinc compound; the zinc compound adheres to the Al-plated steel sheet in an amount of 0.3 to 1.5g/m2 per surface in terms of metallic zinc; and the amount of zinc adhering to an arbitrary continuous area of one square millimeter is 1.5g/m2 or less.
