Abstract

L'invention concerne une tôle d'acier ayant une composition comprenant, en poids : 0,010 % = c = 0,080 %, 0,06 % = mn = 3 %, si = 1,5 %, 0,005 % = al = 1,5 %, s = 0,030 %, p = 0,040 %, ti et b tels que : 3,2 % = ti = 7,5 % et (0,45xti) – 1,35 = b = (0,45xti) – 0,43, éventuellement ni = 1 %, mo = 1 %, cr = 3%, nb = 0,1 %, v = 0,1 %, le reste étant constitué de fer et d'impuretés inévitables résultant de la fusion. La tôle d'acier a une structure consistuée de ferrite, d'au plus 10 % d'austénite, et de précipités comprenant des précipités eutectiques de tib2, la fraction volumique des précipités de tib2 par rapport à la structure totale étant d'au moins 9 %, la proportion des précipités de tib2 ayant une aire inférieure à 8 µm2 étant d'au moins 96 %.
