본 발명은 핫 스탬핑된 구성요소, 핫 스탬핑을 위해서 이용되는 예비코팅된 강 시트, 및 핫 스탬핑 방법에 관한 것이다. 본 발명의 핫 스탬핑된 구성요소는 기본 강의 적어도 하나의 표면 상에서 알루미늄 또는 알루미늄 합금의 코팅을 구비하고, 코팅은 기본 강과 알루미늄 또는 알루미늄 합금의 예비코팅 사이의 상호확산에 의해서 생성되며, 코팅은 6 내지 26 ㎛의 두께를 갖는다. The present invention relates to a hot stamped component, a precoated steel sheet used for hot stamping, and a hot stamping process. The hot stamped component of the present invention is provided with a coating of aluminium or an aluminium alloy on at least one surface of the base steel, the coating is produced by interdiffusion between the base steel and a precoating of aluminium or aluminium alloy, and the coating has a thickness of 6 to 26 µm.
