Abstract (en)
Provided is a hot stamped body which includes a base metal 10, and a plated layer 20 formed on a surface of the base metal 10, wherein the plated layer 20 includes an interface layer 21, an intermediate layer 22, and an oxide layer 23 in order from a base metal 10 side, the interface layer 21 contains an Fe-Al alloy having a microstructure which contains one or more kinds selected from αFe, Fe<sub>3</sub>Al and FeAl, a total area fraction of the Fe-Al alloy being 99% or more, the intermediate layer 22 contains an Fe-Al-Zn phase which contains one or more kinds selected from Fe(Al, Zn)<sub>2</sub>, Fe<sub>2</sub>(Al, Zn)<sub>5</sub>and Fe(Al, Zn)<sub>3</sub>, a total area fraction of the Fe-Al-Zn phase being 50% or more, an average composition of the intermediate layer contains, in mass%, Al: 30 to 50% and Zn: 15 to 30%, and an average film thickness of the oxide layer 23 is 3.0 µm or less, and Mg content in the oxide layer 23 is 0.05 to 0.50 g/m<sup>2</sup>.
