Abstract

L'invention porte sur une tôle d'acier laminée à chaud ayant une épaisseur de tôle de 2 à 15 mm et ayant une composition des composants, en masse, de 0,3 % ou moins de C, 0,5 % ou moins de Si, 0,2 à 1 % de Mn, 0,05 % ou moins de P, 0,05 % ou moins de S, 0,01 à 0,1 % d'Al et 0,008 à 0,025 % de N, le reste étant constitué de fer et d'impuretés inévitables, le N en solution solide représentant au moins 0,007 %. En ce qui concerne les grains cristallins de ferrite situés à la profondeur de t/4 (t représentant l'épaisseur de la tôle d'acier laminée à chaud), la proportion surfacique de grains cristallins au sein d'une orientation de plan de 10° par rapport au plan (123) est d'au moins 20 %, la proportion surfacique de grains cristallins au sein d'une orientation de plan de 10° par rapport au plan (111) est d'au moins 5 %, et la proportion surfacique de grains cristallins au sein d'une orientation de plan de 10° par rapport au plan (001) est inférieure ou égale à 20 % et le diamètre moyen de grain des grains cristallins de ferrite situés à la profondeur de t/4 est de 3 à 35 µm.
