A cutting tool for a wood material having improved performance characteristics is provided. The cutting tool is characterized by a material toughness of more than 100J measured in longitudinal direction as impact energy AV (SBP) pursuant to steel-iron test sheet (SEP) 1314, with a material hardness of more than 60 HRC and increased corrosion resistance as well as wear resistance thereof consisting of an alloy with a chemical composition in % by weight of: C = 0.7 to 0.9 Si = .ltoreq. 0.8 Mn = 0.35 to 0.45 S = < 0.005 Cr = 7.5 to 8.5 Mo = 1.4 to 1.8 Ni = < 0.4 V = 0.5 to 0.7 W = < 0.3 Al = 0.003 to 1.0 Fe = remainder and production-related contaminations. The thermally treated material of the cutting tool has a total carbide content of more than 3% by volume, of which at least 0.35% by volume are monocarbides and the matrix consists of annealed martensite.
Un outil de coupe pour un produit ligneux aux caractéristiques de performance améliorées est divulgué. Il est caractérisé par une résistance du matériau de plus de 100 J mesurée dans le sens longitudinal en tant qu'énergie d'impact AV (SBP) conformément à la fiche de test acier-fer 1314 (SEP), par une dureté du matériau supérieure à 60 HRC et par une résistance accrue à la corrosion ainsi qu'à l'usure Il est constitué d'un alliage ayant la composition chimique suivante en pourcentage massique : C = 0,7 à 0,9, Si = < 0,8, Mn = 0,35 à 0,45, S = < 0,005, Cr = 7,5 à 8,5, Mo = 1,4 à 1,8, Ni < 0,4, V = 0,5 à 0,7, W = < 0,3, Al = 0,003 à 1,0, Fe = le reste, avec des impuretés provenant de la production. Le matériau pour outil de coupe traité thermiquement a une teneur totale en carbure de plus de 3 % en volume, dont au moins 0,35 % en volume de monocarbures, et sa matrice est constituée de martensite recuite.
