WIPO Patent Application WO/2017/051997
Kind Code:
A1
Abstract:
Disclosed is an invention regarding a molded body manufacturing method. The molded body manufacturing method comprises the steps of: preparing first and second steel members; bonding the first and second steel members, thereby manufacturing a bonded steel member; heating the bonded steel member to 910-950ºC; hot-molding the heated bonded steel member using a press, thereby manufacturing an intermediate molded body; and cooling the intermediate molded body, wherein the tensile strength (TS) of the first steel member is higher than that of the second steel member.
