Abstract
Un acier biphasé électro-galvanisé à super-résistance résistant à la fissuration différée est divulgué. Une structure de matrice associée est la ferrite + la martensite revenue et l'acier contient les éléments chimiques suivants dans les pourcentages en masse suivants : C : 0,07 à 0,1 %, Si : 0,05 à 0,3 %, Mn : 2,0 à 2,6 %, Cr : 0,2 à 0,6 %, Mo : 0,1 à 0,25 %, Al : 0,02 à 0, 05 %, Nb : 0,02 à 0,04 %, V : 0,06 à 0,2 %. L'invention concerne également un procédé de fabrication de l'acier biphasé électro-galvanisé à super-résistance résistant à la fissuration différée, le procédé comprenant : la fusion et la coulée continue, le laminage à chaud, le laminage à froid, le recuit, la trempe, l'étalement et l'électroplacage. L'acier biphasé électro-galvanisé à super-résistance résistant à la fissuration différée selon la présente invention présente non seulement de meilleures propriétés mécaniques, mais présente également une excellente résistance à la fissuration différée et une faible teneur en hydrogène initiale.
