Abstract
L'invention concerne une tôle d'acier comprenant, en % en poids, 0,04 = c = 0,30; 0,5 = mn = 4, 0 = cr = 4; 2,7 = mn + cr = 5; 0,003 = nb = 0,1; 0,015 = a1 = 0,1; et 0,05 = si = 1,0; la composition chimique de la tôle thermoformée rend celle-ci insensible à la vitesse de refroidissement après l'austénisation, et permet d'assurer une distribution uniforme de la résistance à la traction, dans la plage de 800 à 1400 mpa, sur toute l'étendue des pièces, indépendamment du décalage entre les opérations de refroidissement/trempe finale. Par conséquent, une partie formée peut être refroidie à l'air ou pendant qu'elle se trouve dans une matrice. L'ajout de nb permet de réduire la quantité de c nécessaire pour obtenir une résistance à la traction donnée, et d'améliorer la soudabilité.The invention relates to a steel sheet comprising, in weight%, 0.04 = c = 0.30; 0.5 = min = 4, 0 = cr = 4; 2.7 = min + cr = 5; 0.003 = nb = 0.1; 0.015 = a1 = 0.1; and 0.05 = si = 1.0; the chemical composition of the thermoformed sheet makes it insensitive to the cooling rate after austenization, and ensures a uniform distribution of the tensile strength, in the range of 800 to 1400 mpa, throughout the extent of parts, regardless of the time lag between cooling / final hardening operations. Therefore, a formed part can be cooled in air or while it is in a die. The addition of nb makes it possible to reduce the quantity of c necessary to obtain a given tensile strength, and to improve the weldability.
