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.
La présente invention concerne un procédé de fabrication d'éléments de structure en acier à haute résistance, selon lequel on procède au formage à froid, par laminage ou analogue, d'une ébauche d'acier laminé à haute résistance présentant une microstructure de ferrite-perlite et des propriétés mécaniques de haute résistance afin d'obtenir un élément de structure d'une coupe transversale géométrique désirée dont la résistance mécanique est sensiblement supérieure ou égale à celle de l'ébauche laminée.
