Abstract

L'invention porte principalement sur une tôle d'acier laminée à chaud de limite d'élasticité supérieure à 680 mpa au moins en sens travers de la direction de laminage, et inférieure ou égale à 840 mpa, de résistance comprise entre 780 mpa et 950 mpa, d'allongement à rupture supérieur à 10% et de rapport d'expansion de trou (ac) supérieur ou égal à 45%, dont la composition chimique consiste, les teneurs étant exprimées en poids : 0,04% = c = 0,08% 1,2% = mn = 1,9% 0,1 % = si = 0,3% 0,07% = ti = 0,125% 0,05% = mo= 0,35% 0,15% = cr= 0,6% lorsque 0,05% = mo= 0,11%, ou 0,10% = cr= 0,6% lorsque 0,11 % = mo= 0,35% nb = 0,045% 0,005% = al = 0,1 % 0,002% = n = 0,01% s = 0,004% p=0,020% et optionnellement 0,001 % = v = 0,2% le reste étant constitué de fer et d'impuretés inévitables provenant de l'élaboration, dont la microstructure est constituée de bainite granulaire dont le pourcentage surfacique est supérieur à 70%, et de ferrite dont le pourcentage surfacique est inférieur à 20%, le complément éventuel étant constitué de bainite inférieure, de martensite et d'austénite résiduelle, la somme des teneurs en martensite et en austénite résiduelle étant inférieure à 5%. L'invention porte également sur le procédé de fabrication d'une telle tôle.
