Abstract
L'invention fournit une tôle d'acier galvanisée à chaud par immersion et une tôle d'acier alliée galvanisée à chaud par immersion de 980MPa ou plus qui se révèlent excellentes en termes de propriétés de placage, de propriétés d'usinage, plus particulièrement concernant l'équilibre entre résistance et étirement et la flexibilité, et de résistance à la fracture différée. La tôle d'acier plaquée hautement résistante de l'invention possède une couche de plaquage à la surface d'une tôle d'acier de base, comprend des composants d'acier prédéfinis, et possède dans l'ordre depuis une interface entre la tôle d'acier de base et la couche de placage vers un côté tôle d'acier de base : une couche souple dont la dureté de Vickers, lorsque l'épaisseur de ladite tôle d'acier de base est représentée par t, satisfait 90% ou moins de la dureté de Vickers dans une partie t/4 de ladite tôle d'acier de base ; et une couche dure comprenant dans une plage prédéfinie une martensite ainsi qu'une bainite, et une ferrite. La profondeur moyenne (D) de la couche souple est supérieure ou égale à 20μm, et la profondeur moyenne (d) d'une couche oxydée de partie interne est supérieure ou égale à 4μm et inférieure à la profondeur moyenne (D).
