Title
(EN) COLD FORMED HIGH-STRENGTH STEEL STRUCTURAL MEMBERS
(FR) ELEMENTS DE CHARPENTE PROFILES A FROID EN ACIER EXTREMEMENT RESISTANT
Abstract
(EN)
A method of making high-strength steel structural members is disclosed by providing a blank of high-strength steel having a ferrite-pearlite microstructure and high-strength mechanical properties and cold forming the blank by rolling, upsetting, forging, or extrusion 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 blank.
(FR)
Procédé de fabrication d'éléments de charpente en acier extrêmement résistant au moyen d'une ébauche en acier extrêmement résistant possédant une microstructure de ferrite-perlite, ainsi que des propriétés mécaniques de résistance élevée, qu'on profile à froid par laminage, frappe à froid, forgeage ou extrusion, afin d'obtenir un élément de charpente présentant une section transversale géométrique souhaitée, tandis que sa résistance mécanique reste sensiblement égale ou supérieure à celle de l'ébauche.
