Abstract
L'invention concerne une tôle d'acier à haute résistance présentant une aptitude au traitement par conversion chimique et une résistance à la corrosion post-électrodéposition supérieures, même lorsque la quantité de Si contenue est importante. L'invention concerne également un procédé de production associé. Selon ce procédé, une tôle d'acier contenant, en % en masse, 0,01-0,18% de C, 0,4-2% de Si, 1-3% de Mn, 0,001-1% de Al, 0,005-0,060% de P et S=0,01%, le reste étant constitué de Fe et d'impureté inévitables, est recuite en continu, la plage de températures du four de réchauffage, pendant un processus de réchauffage, de A°C à B°C inclus (A: 600=A=780 ; et B: 800=B=900) présentant un point de rosée de l'air ambiant d'au moins -10°C.
