Abstract
Produit en acier ou bande moulée en acier mince comprenant en poids moins de 0,25 % de carbone, entre 0,20 et 2,0% de manganèse, entre 0,05 et 0,50% de silicium, moins de 0,01% d'aluminium, et entre 0,01% de niobium et 0,20% et/ou entre 0,01% et 0,20% de vanadium, ce produit ou cette bande possédant une microstructure qui contient majoritairement de la bainite et de la ferrite aciculaire et plus de 70% de niobium et/ou de vanadium dans une solution solide. Le produit en acier peut présenter une augmentation de son élongation et de sa limite d'élasticité après avoir durci par vieillissement. Le produit en acier durci par vieillissment peut comprendre des particules de carbonitrure de niobium à taille granulométrique moyenne d'au moins 10 nanomètres et pratiquement pas de particules de carbonitrure de niobium supérieures à 50 nanomètres. Le produit en acier peut avoir une limite d'élasticité d'au moins 380 MPa ou une résistance à la traction d'au moins 410 MPa ou les deux à la fois. Le produit en acier ou la bande moulée, en acier, mince a une élongation totale d'au moins 6% ou 10%.
