Abstract
L'invention concerne un produit en acier ou une mince bande en acier coulé constitué(e), en poids, de 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 soit le niobium entre 0,01% et 0,20% en poids, soit le vanadium entre 0,01% et 0,20% en poids, ou les deux, et possédant une microstructure avec une majorité de bainite et de ferrite aciculaire, et plus de 70% de niobium et/ou de vanadium en solution solide. Le produit en acier peut avoir une augmentation en allongement ainsi qu'une augmentation de la limite d'élasticité après durcissement par vieillissement. Le produit en acier durci par vieillissement peut avoir des particules de carbonitrure de niobium ayant une taille particulaire moyenne de 10 nanomètres et moins, et n'avoir sensiblement aucune particule de carbonitrure de niobium supérieure 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. Le produit en acier ou la mince bande en acier coulé peut avoir un allongement total d'au moins 6% ou 10%.
