Abstract

L'invention concerne une plaque ou tôle d'acier résistant à l'abrasion qui présente d'excellentes propriétés en termes de ténacité d'une soudure et de résistance à la rupture différée, et qui convient donc pour des engins de construction ou des machines industrielles, entre autres. Une plaque ou tôle d'acier spécifiquement décrite contient, en pourcentage massique, 0,20 à 0,30 % de C, 0,05 à 1,0 % de Si, 0,40 à 1,2 % de Mn, 0,010 % ou moins de P, 0,005 % ou moins de S, 0,40 à 1,5 % de Cr, 0,005 à 0,025 % de Nb, 0,005 à 0,03 % de Ti, 0,1 % ou moins d'Al, 0,01 % ou moins de N, et si nécessaire au moins un élément choisi parmi Mo, W, B, Cu, Ni, V, les terres rares, Ca et Mg. Elle présente un DI* de 45 à 180, tout en satisfaisant la relation C+Mn/4-Cr/3+10P = 0,47. Sa microstructure contient de la martensite comme phase matricielle. DI*=33,85×(0,1×C)0,5×(0,7×Si+1)×(3,33×Mn+1)×(0,35×Cu+1)×(0,36×Ni+1)×(2,16×Cr+1)×(3×Mo+1)×(1,75×V+1)×(1,5×W+1).
