Abstract

See full text

A method for producing a molded article includes the steps of: preparing a first steel plate and a second steel plate. The first steel plate and the second steel plate are joined to each other, thereby preparing a joined steel plate. The joined steel plate is heated at a temperature between 910° C. and 950° C. The heated joined steel plate is then subjected to hot-press molding, thereby preparing an intermediate molded article; and cooling the intermediate molded article, wherein the first steel plate has a tensile strength (TS) higher than that of the second steel plate.
