Beschreibung
Zusammenfassung:	Disclosed herein is a method for warm forming of a super high tensile strength steel sheet. The method may improve productivity and simultaneously maintain accurate strength by securing thermal structure stability and dimensional stability during heating and forming the super high tensile strength steel sheet. According to an exemplary embodiment of the present invention, the method for warm forming of a super high tensile strength steel sheet includes: heating a steel sheet having a single-phase structure at Al transformation temperature or less; pressing, in a mold, the heated steel sheet to be formed in a predetermined shape; and extracting and cooling the pressed steel sheet.
