Fe-Al plating hot stamp member and method for manufacturing Fe-Al plating hot stamp member

摘要

An object of the present invention is to provide a method for manufacturing a Fe-Al-based plated hot stamp member and a Fe-Al-plated hot stamp member, which exhibit better corrosion resistance and post-painting corrosion resistance of a molded part. The hot stamp member according to the present invention has a Fe-Al-based plating layer located on one or both surfaces of the base material, the base material has a predetermined steel component, and the Fe-Al-based plating layer has a thickness of 10 µm. It is more than 60 µm or less, and is composed of four layers of A layer, B layer, C layer, and D layer in turn toward the base material from the surface, and each of the four layers is Al, Fe, Si, Mn, and Cr. a is made of a predetermined amount contained, and the balance being impurities of Fe-Al intermetallic compound into, D layer, also, the larger cross-sectional area is not more than the void Kendall 3㎛ ² or more 30㎛ ^2, 10 gae / 6000㎛ ² It contains more than 40 pieces/6000㎛ ² or less.
