Abstract

The object of the invention is to improve the performance characteristics of a cutting tool for wood material.
According to the invention, the cutting tool is characterized by a material toughness of more than 100J measured in longitudinal direction as impact energy AV (SBP) pursuant to Stah1-Eisen-Prüfblatt [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 = <= 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 as well as production-related contaminations, wherein 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.

Claims (5)

1. A cutting tool, in particular knives for machining wood as well as for products with wood, such as chipboards and the like, having a material toughness of more than 100J
measured in longitudinal direction as impact energy AV
(SBP) pursuant to Stahl-Eisen-Prüfblatt [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 = <= 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 as well as production-related contaminations, wherein 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.
2. The cutting tool according to claim 1, wherein the alloy has an A1 content of 0.15 to 0.25% by weight.
3. The cutting tool according to claim 1 or 2, whose surface zone has an increased nitrogen content.
4. The cutting tool according to any one of the claims 1 to 3, which has a coating which is preferably formed as a compound with carbon and/or nitrogen and/or oxygen.
5. The cutting tool according to claim 4, in which the coating contains a chromium compound.
