Abstract

L'invention concerne une feuille d'acier laminée à froid, durcissable à la cuisson dotée d'une résistance élevée et d'une résistance supérieure au vieillissement et utilisée avec des panneaux externes d'une carrosserie d'automobile, une feuille d'acier galvanisée utilisant ladite feuille d'acier laminée à froid, et un procédé de fabrication de la feuille d'acier laminée à froid. Ladite feuille d'acier comprend en pourcentage pondéral : C: 0,0016 ~ 0,0025 %, Si: 0,02 % au maximum, Mn: 0,2 ~ 1,2 %, P: 0,05 ~ 0,11 %, S: 0,01 % au maximum, Sol. Al: 0,08 ~ 0,12 %, N: 0,0025 % au maximum, Ti: 0 ~ 0,003 %, Nb: 0,003 ~ 0,011 %, Mo: 0,01 ~ 0,1 %, B: 0,0005 ~ 0.,0015 %, le reste de Fe et d'autres impuretés inévitables. Ladite feuille d'acier présente une capacité de durcissement à la cuisson supérieure, une résistance au vieillissement à température ambiante, et une résistance à la fragilisation d'un travail secondaire.
