Definitions

the invention relates to a cutting tool, in particular a knife for a wood chip.
Knives made of this steel have a high material toughness in the thermally tempered state, but their wear resistance, the dimensional stability of the cutting area and the corrosion resistance are usually too low.
knives or blade strips are often made of steel according to material no. 1.2363 manufactured, which cutting tools usually have no sufficient wear resistance. It has already been tried, as a cutting tool material according to an alloy AT 393 387 B respectively.
EP 0425471 A1 with the best results in terms of wear behavior, but occasionally errors occurred which pointed to too low material toughness.
the invention has the object to overcome the respective disadvantages of the prior art and to provide a cutting tool, in particular a knife, of the type mentioned, which due to a narrow selection of the concentration of the respective elements in the steel or the chemical composition and the thermal compensation and the microstructure of the material synergistically improved performance characteristics in a machining, in particular a chip, wood with intermittent load or interrupted cut.
a high toughness of the tool material has been found to be required because at a stroke value measured on a percussion test in the longitudinal direction of less than 100J, breakouts at the cutting edges and even knife breaks may occur.
high material hardness values which ensure a high dimensional stability of the entire cutting area at high impact loads are necessary.
a hardness of less than 60 HRC allows plastic deformation of the tool material, which can lead to a deterioration of the tool function in the cutting operation.
the concentration of the respective alloying elements is important in accordance with the invention because they determine the precipitation and transformation kinetics and the microstructure in the case of a thermal treatment.
the content of carbon is to be considered simultaneously with the content or the activity of the respective carbide-forming elements in relation to carbon.
carbon produced by 0.5 to 0.7 wt .-% vanadium monocarbides, which have a small diameter, and are homogeneously distributed and thus with a content of at least 0.35 vol .-% make a significant contribution to the wear resistance of the material without negatively affecting its toughness.
Higher levels of carbon and vanadium may be detrimental to the interaction of the alloying elements and tend to result in coarser carbide structure, thereby degrading material toughness.
Low concentrations of these elements of less than 0.7% by weight Carbon and 0.5 wt .-% vanadium reduce disproportionately the wear resistance of the material.
the carbon content of the alloy is also defined with respect to a shaping of M 7 C 3 and M 23 C 6 carbides with the other carbide-forming elements of the steel in the range of 0.7 to 0.9 wt .-%, with what content the desired properties of the matrix consisting of tempered martensite can be achieved.
the respective concentration of chromium and molybdenum in the range of 7.5 to 8.5 or 1.4 to 1.8 are essential for a desired total carbide content of greater than 3.0 vol .-%, however, is a material embrittling effect because of Tungsten content limited to a value of less than 0.3 wt .-%.
Manganese at levels of 0.35 to 0.45, promotes hardenability of the steel and binds the sulfur, which is believed to have a concentration level below 0.005 weight percent, to manganese sulfide.
Nickel has a disruptive effect on the precipitation and conversion kinetics of this cutting steel in a tempering treatment, so that a Ni content of less than 0.4% by weight is essential for the desired quality of the tool.
the inventively provided content of aluminum in the steel within the limits of 0.003 to 1.0 wt .-% on the one hand has a particularly favorable effect on the hardness and tempering behavior or on the remuneration structure and the mechanical properties of the material, on the other hand by aluminum as well the quality of a surface layer, such as a nitride layer, or the adhesion of a coating, such as a deposited after the PVD or CVD nitride, carbonitride or oxide carbonitride layer of metals, in particular of titanium and / or chromium promoted.
Aluminum increases the activity and the diffusion coefficient of carbon in austenite.
the diffusion coefficients of chromium, molybdenum and vanadium are reduced by aluminum in the austenite and in the ferrite. This means a reduction in the solubility of carbon in the austenite, so that the stability of the austenite is lowered and therefore the martensite starting point is increased, which in turn reduces the residual austenite content in the austenite hardened structure is greatly lowered.
Aluminum is mainly dissolved in the matrix and contributes to the solid solution hardness. The high affinity of aluminum for nitrogen increases the hardness of the diffusion layer of nitrided steels.
An aluminum content of 0.15 to 0.25 wt .-% in the alloy is preferred.
a "chipper knife” made according to the invention parallel to the testing tool, was used in a device for cutting logs in difficult conditions by adhering earth particles and provided the market in comparison with a high-performance knife arranged next to it Service life improvement of 120%.
