| description | According to the present invention, a manufacturing method for molded articles is disclosed. The manufacturing method for molded articles comprises the following steps of: preparing a first steel material and a second steel material; manufacturing a binding steel material by binding the first steel material and the second steel material; heating the binding steel material at 910-950C; manufacturing intermediate molded articles by hot press forming the heated binding steel material; and cooling the intermediate molded articles. Moreover, tensile strength (TS) of the first steel material is higher than that of the second steel material.
성형체 제조방법에 대한 발명이 개시된다. 상기 성형체 제조방법은 제1 강재 및 제2 강재를 마련하는 단계; 상기 제1 강재 및 제2 강재를 접합하여 접합강재를 제조하는 단계; 상기 접합강재를 910℃~950℃로 가열하는 단계; 상기 가열된 접합강재를 열간 프레스 성형하여 중간성형체를 제조하는 단계; 및 상기 중간성형체를 냉각하는 단계;를 포함하며, 상기 제1 강재는 상기 제2 강재보다 인장강도(TS)가 높은 것을 특징으로 한다. |
