<p>The present invention relates to a steel sheet for hot press forming and, more specifically, to a steel sheet for hot press forming to be applicable to automobile components and the like and a manufacture method thereof. The purpose of the present invention is to provide a method for effectively preventing liquefied brittle fracture during the hot press forming (HPF) of a galvanized steel sheet and a steel sheet for hot press forming manufactured by the same. The manufacturing method of a steel sheet for hot press forming comprises: a step of preparing a base material steel sheet; a step of manufacturing a plated steel material by forming a plating layer on the base material steel sheet; a step of heating the plated steel material; and a step of rapidly cooling the plated steel material immediately after heating.</p> |
