Abstract
The present invention provides a hot stamp moulded body which takes into consideration problems to be solved in the prior art, achieves high bendability, high ductility, and hydrogen embrittlement resistance characteristics in order to achieve impact resistance characteristics, and suppresses variation in hardness. A hot stamp moulded body according to the present invention is characterized by being provided with a plate thickness central portion, and a softened layer provided to one or both sides of the plate thickness central portion. The hot stamp moulded body is further characterized in that: the plate thickness central portion has a hardness in the range of 500-800 Hv inclusive; and, in the metal structure from a depth of 20 µm below the surface of the softened layer to a depth of ½ of the thickness of the softened layer, when areas surrounded by grain boundaries having a misorientation of 15Ë or higher, in a cross section parallel to the plate thickness direction, are defined as crystal grains, the total area ratio of crystal grains having a maximum crystal misorientation of 1Ë or lower inside the crystal grains defined above, and crystal grains having a maximum crystal misorientation in the range of 8-15Ë inclusive inside the crystal grains defined above is at least 50 %, but less than 85%.
