Definitions
- the invention relates to a steel for cutting tools.
- Cutting edges of tools are at a chip removal of Workpieces essentially thermal, abrasive and toughness and High pressure load, the stress of the Tool material is carried out simultaneously.
- Loading profiles to achieve maximum tool life are respective Alloy compositions that meet the peak profile requirements wear, largely belonging to the state of the art.
- High cutting strength of a tool can generally with the use High speed steels are achieved, however, high levels of the the expensive alloying element (s) molybdenum and / or tungsten in Have concentrations up to 20 wt .-%. Vanadin is one of them Elements and is used in common or PM high speed steels with grades of 1.2 up to 10.0 wt .-% alloyed.
- high speed steels can be required for one Stress profile to the tool in terms of composition favorable but have the disadvantage of high alloy and therefore Material costs. Now, for economic reasons, a concentration of Main alloying elements lowered, so can often jump the thermal Quenchability, hardness and general usability of the steel deteriorate.
- the invention is based on the object, the shortcomings of the prior art eliminate and create a steel by alloying Measures for cutting tools has particularly good suitability and has high economy.
- Vanadium may be partially replaced by niobium in the alloy up to 0.45% by weight, however, in these cases the carbon content is in the lower range of To set the concentration limit.
