Abstract

La présente invention se rapporte à une tôle d'acier basse température, qui peut être utilisée sur une large plage de température allant d'une basse température à la température ambiante, dans des réservoirs de stockage de gaz liquéfié et des installations de transport. L'invention concerne : une tôle d'acier basse température ayant une excellente qualité de traitement de surface, même après la réalisation d'un processus de traitement, tel qu'un processus de tension; et son procédé de fabrication. Un aspect de la présente invention concerne une tôle d'acier basse température ayant une excellente qualité de traitement de surface, la tôle d'acier basse température contenant du manganèse (Mn, de 15 à 35 % en poids), du carbone (C, satisfaisant à 23,6C + Mn = 28 et 33,5C - Mn = 23), du cuivre (Cu, 5 % en poids ou moins, à l'exclusion de 0 % en poids), du chrome (Cr, satisfaisant à 28,5C + 4,4Cr = 57 à l'exclusion de 0 % en poids), du titane (Ti, de 0,01 à 0,5 % en poids), de l'azote (N, de 0,003 à 0,2 % en poids), le reste étant constitué de fer (Fe) et d'autres impuretés inévitables, Ti et N satisfaisant à la relation 1 ci-dessous. [Relation 1] 1,0 = Ti/N = 4,5 (à condition que Mn, C, Cr, Ti et N, dans les expressions respectives, désignent le pourcentage % en poids du contenu de l'ingrédient considéré).
