Abstract

Eléments en acier très résistant et procédé de production associé dans lequel on utilise une ébauche de matériau en acier très résistant dont la résistance à traction est au moins égale à environ 120 000 psi et la limite élastique est au moins égale à environ 90 000 psi, puis on forme à semi-chaud l'ébauche pour produire l'élément ayant la configuration géométrique désirée tout en conservant ou en augmentant sensiblement les propriétés de résistance de l'ébauche.
