摘要： A method of making high-strength steel structural members is disclosed by providing a flat-rolled blank of high strength steel having a ferrite-pearlite microstructure and high-strength mechanical properties and cold forming the blank by rolling or the like to provide a structural member having a desired geometric cross-section while the mechanical strength of the structural member remains substantially the same or greater than the flat-rolled blank.

摘要： 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.
