Abstract

The present invention refers to a method for attaining a reduction of the rupture and tensile limit of a blank or profile of an ultra-high strength material. According to the method the blank or profile is exposed to a heat treatment by heating to above 300 DEG C within selected portions of the sheet. <IMAGE>
