Definitions
- the invention relates to a high-speed steel object with high heat resistance and toughness, powder metallurgically by breaking up a liquid Metal stream of an alloy with nitrogen to metal powder and compacting the Powder made at high temperature under all-round pressure and if necessary, is thermoformed.
- High-performance high-speed steels comprise alloys with about 0.8 to 1.0% by weight Carbon, 14 to 18% by weight tungsten, about 4.5% by weight chromium, up to 2% by weight Molybdenum, at least 1.2 to 1.5% by weight molybdenum, at least 1.2 to 1.5 % By weight vanadium and 3 to 20% by weight cobalt, balance iron.
- the cause of having The high performance achievable with these high-speed steels lies in the interaction the strongly carbide - forming elements vanadium, tungsten, molybdenum and chrome and the element cobalt, which acts via the matrix or the matrix.
- Tungsten and molybdenum are particularly suitable for vanadium
- the alloy a high one Temper resistance up to a temperature of about 600 ° C to impart. at high carbon and high vanadium content also become large Amount of vanadium carbides formed by which a special Wear resistance of the material is effected.
- finishing tools are therefore made with high-speed steels, which have an increased carbon and Show vanadium content, manufactured.
- a powder metallurgical production essentially involves atomizing one Melting steel into metal powder, introducing and compacting the metal powder into a capsule, closing the capsule and heating and hot isostatic Pressing the powder in the capsule into a dense, homogeneous material.
- This PM material can be used immediately after appropriate heat treatment Manufacture of objects used or previously a hot forming, for Example by forging.
- Heavy duty high speed steel objects, especially Cutting tools with a long service life, for economical machining of Parts require a multi-layered high property profile.
- the invention is based on the object, a high-speed steel object, preferably to create one for a high-performance cutting tool, which has a high oxide purity, so a low one Crack initiation potential and an increased degree of sharpness of the cutting edges has high hardness with adequate toughness and high wear resistance in the thermally tempered condition of the material as well as improved warm hardness or has high heat resistance.
- Another object of the invention is to provide a High speed steel object for use as a tool for one High speed machining of materials without the addition of Lubricants, in particular for machining Light metals and such alloys.
- this specification is achieved in the case of a high-speed steel object of the type mentioned at the outset in that the object has a high degree of purity with a content and configuration of non-metallic inclusions corresponding to a value K0 of at most 3 in accordance with the test according to DIN 50 602 and the following chemical composition % Carbon (C) 1.51 to 2.5 Silicon (Si) to 0.8 Manganese (Mn) to 1.5 Chrome (Cr) 3.5 to 4.5 Tungsten (W) 13.3 to 15.3 Molybdenum (Mo) 2.0 to 3.0 Vanadium (V) 4.5 to 6.9 Cobalt (Co) 10.05 to 12.0 Sulfur (S) to 0.52 Nitrogen (N) up to 0.3 Oxygen (N) max 100 ppm with a value: manganese minus sulfur (Mn-S) of at least 0.19, iron and manufacturing-related impurities and accompanying elements as the remainder, with the proviso that the ratio of the concentrations of tungsten to molybdenum is
- the excellent property profile of the alloy according to the invention results synergistic from the interaction of the elements in their respective activities. It is essential that the concentration values in high-speed steel Carbon, chromium, tungsten, molybdenum, vanadium and cobalt within narrow limits are present and that the oxygen content does not exceed a maximum value.
- the Carbon in the light of the high affinity of the elements is tungsten, Molybdenum and vanadium to see this.
- the above alloy metals form stable However, primary carbides and secondary hardness carbides are also after interaction and the respective activity in the matrix mixed crystals.
- the carbon concentration of the alloy is 1.51 to 2.5% by weight.
- the chromium concentration with a maximum value of 4.5% by weight is thereby justified because higher levels lead to a chromium content in the matrix, the has a stabilizing effect on the residual austenite content during hardening.
- Up to one The minimum value of 3.5% by weight of chromium is achieved by installing the alloy atoms a desired solidification of the same in the mixed crystal, so that according to the invention a content range of 3.5 to 4.5% by weight is provided in the material.
- Tungsten and molybdenum have a high carbon affinity, almost form similar carbides and are in the widely represented opinion of the professional world Due to the respective atomic weight mass-exchangeable 2 to 1. It was surprisingly found that this interchangeability was not is completely given, but by the respective activity of this Alloy elements the mixed carbide formation and the proportion of elements in the Mixed crystal are controllable, whereupon when discussing the heat resistance of the High-speed steel is discussed in more detail.
- Vanadium is one of the strongest monocarbide formers, whose carbides are characterized by high Characterize hardness and the special wear resistance of the material justify.
- the wear resistance is due to the fine training and an im essentially homogeneous distribution of the monocarbides, such as this by a powder metallurgical manufacturing of the material is promoted.
- vanadium but also the elements tungsten and molybdenum partially bring high temperatures into solution, which after a forced Cooling the object through a substantial secondary hardness potential Excretion of finely divided secondary carbides rich in vanadium Tempering treatments and beneficial to the heat resistance of the material is effective.
- Vanadium concentrations below 4.5% by weight lead to a significant deterioration in the wear behavior of the tempered Part.
- Cobalt is not a carbide-forming element in high-speed steel, but it solidifies it Matrix and significantly promotes the thermal resistance of the object. Height Cobalt contents of more than 12.0% by weight work in the given high-speed steel embrittling to the basic mass of the material, whereas less Concentrations than 10.05% by weight significantly reduce the matrix hardness cause increased temperature.
- Cobalt within the limits of 10.05 to 12.0% by weight provided according to the invention causes due to the high diffusion coefficient that when starting the hardened part due to the increased nucleation, the diffusion processes facilitated and thus the secondary carbide excretion in large numbers and large
- the amount should be finely divided, and only coarsen slowly beneficial to matrix strength, especially at high temperature are.
- the fine secondary carbides are by diffusion processes at high Application temperatures increased or coagulation takes place.
- a high tungsten content in the alloy and consequently in the Secondary carbides are smaller due to the size of the tungsten atoms Diffusion coefficient compared to the elements molybdenum and vanadium, so that a significantly slower coarsening and stabilization of the system at high Temperature, as was found, also occurs with mixed carbides.
- the Tungsten content of 13.3 to 15.3% by weight according to the invention secures the predetermined contents of the other strongly carbide-forming elements a low Tendency to coarsen the secondary hardness carbides at elevated temperatures and therefore a small carbide particle spacing over the long term, which leads to dislocations blocked in the matrix grid and a softening of the material dilated.
- the material remains hard for longer even under high thermal loads, so it has one increased heat resistance.
- the molybdenum is one of the reaction kinetics or mixed carbide formation essential importance, with a content of 2.0 to 3.0 as according to the invention was effectively determined.
- a maximum content of 100 ppm oxygen is in terms of the number of non-metallic inclusions and the property profile of the material in the Stresses provided.
- the material is the ratio of the concentrations of tungsten and molybdenum the cobalt concentration matched to these elements. At values of tungsten for molybdenum contents from 5.2 to 6.5 is the rate of secondary carbide particle coarsening and thus a drop in hardness of the material at high Temperatures minimized, with a content less than 70% cobalt, measured on the tungsten + molybdenum concentration, an increase in the number of germ sites for one Formation of secondary carbides causes a finely dispersed distribution the same promotes what is overall a high heat resistance of the High-speed steel object.
- Silicon in the alloy has solid-solution strengthening and deoxidizing effects, However, due to the hardenability of the material, it should contain 0.8 Do not exceed% by weight.
- Manganese can influence the hardness behavior of the material, but it is primarily seen together with the sulfur content, with sulfur and Manganese as steel workability enhancing elements Sulphide inclusion formation can be seen. With preferably low manganese contents in steel, the value: manganese minus sulfur should not fall below 0.19, because it contributes to hot forming problems and reduced material properties high usage temperatures can arise.
- Nitrogen can develop due to the formation of sparingly soluble at high temperatures Carbonitrides in the material according to the invention have a favorable effect on Have improvement in heat resistance, but should only be up to a content of 0.2% by weight may be added to avoid manufacturing problems.
- the high-speed steel in embodiments of the invention to further improve the usage properties of the high-speed steel, on the basis of the above composition, it can have one or more elements with the following concentration value (s) in% by weight.
- concentration value s in% by weight.
- a further narrowing of the concentration range of alloy components can be used advantageously for targeted material alignment for special applications, the object having one or more elements with the following concentration value (s) in% by weight based on the first-mentioned composition C 1.69 to 2.29 Si 0.20 to 0.60 Mn 0.20 to 0.40 Cr 3.59 to 4.19 W 13.60 to 14.60 Mo 2.01 to 2.80 V 4.55 to 5.45 Co 10.40 to 11.50 N 0.02 to 0.1 (O) max 90 ppm
- the further object of the invention is achieved by using a high-speed steel cutting tool with high heat resistance and toughness, which is produced by powder metallurgy by splitting a liquid metal stream of an alloy with nitrogen into metal powder and compacting the powder at high temperature under all-round pressure and optionally thermoformed has a high degree of purity with a content and configuration of non-metallic inclusions corresponding to a value K0 of at most 3 according to the test according to DIN 50 602 and the following chemical composition in% by weight C 1.51 to 2.5 Si to 0.8 Mn to 1.5 Cr 3.5 to 4.5 W 13.3 to 15.3 Mo 2.0 to 3.0 V 4.5 to 6.9 Co 10.05 to 12.0 S to 0.52 N up to 0.2 O max 100 ppm with a value: manganese minus sulfur (Mn-S) of at least 0.19, iron and manufacturing-related impurities and accompanying elements as the remainder, with the proviso that the ratio of the concentrations of tungsten to molybdenum is between 5.2 and 6.5 and that the cobalt content is at
