La dureté d'un acier de l'invention est d'au moins 56 HRC à l'état durci. Pour cela, la structure de l'acier contient au total au moins 30% en poids de phases dures qui sont constituées, en plus des particules de TiC, d'autres particules de carbure, particules d'oxyde ou particules de nitrure. La teneur en particules de TiC dans l'acier de l'invention est d'au moins 20% en poids. Les particules de phase dure sont incorporées dans une matrice constituée (% en poids) de 9,0 à 15,0% de Cr, de 5,0 à 9,0% de Mo, de 3,0 à 7,0% de Ni, de 6,0 à 11,0% de Co, de 0,3 à 1,5% de Cu, de 0,1 à 2,0% de Ti, de 0,1 à 2,0% d'Al, le reste étant du fer et des impuretés inévitables. Sa combinaison de propriétés rend l'acier de l'invention particulièrement approprié à la production de composants, en particulier de couteaux ou de plaques perforées qui sont nécessaires dans la production et le recyclage de matières plastiques.
