Definitions
- the invention relates to the use of an iron-based alloy with a special composition as a material for the powder metallurgical production of parts with high corrosion resistance, high wear resistance and high toughness and pressure resistance, preferably for plastic molds, machine parts and tools for non-cutting shaping.
- a material for the powder metallurgical production of parts with high corrosion resistance, high wear resistance and high toughness and pressure resistance preferably for plastic molds, machine parts and tools for non-cutting shaping.
- shaping parts are exposed to chemical and abrasive stresses at the same time, these parts having to have high material toughness, high compressive strength and special material homogeneity due to the mechanical stresses.
- Such requirements are placed, for example, on materials that are used in devices for pressing fiber-reinforced or filler-containing plastics. Austenitic steels or chrome steels with a chromium content of approx.
- alloys according to DIN material no. are used for mechanical components such as screws etc. and also for forming and pressing tools, which are particularly exposed to corrosive stresses. 1.4528. Although such materials have sufficient corrosion resistance, the wear behavior is usually unsatisfactory in practical operation. In order to improve or increase the wear resistance and hardness of the steel, attempts have also been made by higher carbon contents to increase the carbide content of the alloy. These steels, for example alloys according to DIN material no. 1.2080 and material no. 1.2379, with a carbon content of approx. 2% and a chromium content of approx.
- the object of the invention is to avoid the above disadvantages and, in particular, to create materials which can be used advantageously for the plastics processing industry and which, due to a special composition when using certain manufacturing processes, provide high corrosion resistance, high wear resistance and high pressure resistance have good toughness properties.
- the invention therefore relates to the use of an iron-based alloy with a composition in% by weight.
- the alloy proportions in% by weight chrome 18.0 - 25.0 molybdenum 0.6 - 1.7 tungsten 0.5 - 1.5 Vanadium 3.5 - 5.6 nitrogen 0.03-0.1 niobium up to 5.0 titanium up to 5.0 boron to 0.03
- the material has a niobium content of 0.2 to 3.0 and / or a titanium content of 0.2 to 3.5 and / or a boron content of 0.001 to 0.002. It is particularly preferred if the value is formed from (% Cr - 13) + 4.4x (% V - 3) + 2x (% Nb) + 4.2x (Ti) is at least 10.0.
- the parts which are manufactured from the alloy according to the invention or from the material according to the invention by a powder metallurgical manufacturing process must have a chromium concentration in all parts of the matrix of at least 13 after hardening and tempering.
- the alloy according to the invention from a minimum value, which takes into account the concentrations and the respective effect with the mutual influence of the carbide-forming elements chromium, vanadium, niobium and titanium, and which in particular determines the wear resistance of the material, in certain narrow Limits set carbon contents and when using powder metallurgical manufacturing processes, materials that have high corrosion resistance, high wear resistance, high pressure resistance and high toughness and are advantageous, especially for the construction of plastic molds, can be used, the hardened and tempered state of the Chromium content in all areas of the matrix and the proportion as well as the composition and the grain size of the carbides can be adjusted according to the invention.
- Silicon as a deoxidizing agent influences the composition of the oxides and, in small concentrations, can be advantageous for good polishability from Le manufactured parts. Levels above 1% by weight, however, have an adverse effect on the solidification behavior and, if appropriate, on the conversion processes during the heat treatment. Manganese contents of up to 1% by weight may be important for sulfur contents of up to 0.03% by weight in order to bind the sulfur as sulfide and thereby improve the toughness of the material. Phosphorus has an embrittling effect and should be present in the steel as low as possible, but below 0.03% by weight. Chromium acts as an alloying element which, from a content of approx. 13% by weight in the matrix, makes the material resistant to corrosion.
- chromium is a carbide former that can also form M23C6 carbides with carbon in certain carbon activities and in the presence of molybdenum and vanadium in addition to M7C3 carbides. It is therefore important that the steel contains at least 16% by weight of chromium, but at most contains 29% by weight of chromium, because higher chromium concentrations lead to embrittlement of the material. Molybdenum in a content of 0.4 to 2.5 wt .-% and tungsten in a content of 0.3 to 2.0 wt .-% cause an increase in secondary hardness in the heat treatment by the formation of fine carbides and are used to adjust the carbon activity Alloy important.
- Vanadium as a strong carbide former, causes the formation of MC carbides, especially at levels above 0.7 to 3% by weight. Higher contents, in particular over 10%, lead to an improvement in wear resistance, but the toughness of the parts deteriorates considerably. Titanium up to 5% by weight improves the wear resistance of the material, in particular through MC carbide formation. Due to nitride formation, nitrogen contents from 0.01% have a grain-refining effect or prevent grain growth during annealing at high temperatures tures, whereby a decrease in the toughness of the alloy is avoided. Furthermore, wear resistance can be improved by nitrogen concentrations up to 0.18%.
- Aluminum can be alloyed as an element with a high affinity for oxygen and a high affinity for nitrogen in concentrations of up to 1% by weight to adjust the low oxygen content of the steel and to avoid grain growth, whereby advantageous effects on the conversion behavior and the toughness of the material can also be achieved. It was also found that a minimum value of the alloy, formed from the concentrations of the carbide- and nitride-forming elements chromium, tungsten, niobium, titanium and certain action factors of these elements is required for the setting of the desired mechanical properties of the part, by increasing this Worth an improvement in wear resistance and compressive strength with a slight decrease in toughness.
- the carbon content is set within narrow limits depending on the contents and on certain operating parameters of the carbide-forming elements in the steel in order to obtain the desired properties of the parts.
- MC carbides are formed for matrix hardening and to obtain high compressive strength M7C3, M23C6 and M6C carbides and for setting high wear resistance, but on the other hand there is a chromium content of greater than 13% required for corrosion resistance in all areas of the matrix.
- Powder-metallurgical production of the parts is essential because this significantly improves their isotropy of the properties of the material and the grain size of the precipitates or intermetallic phases can be kept small.
- Carbides with grain sizes over 14 ⁇ m significantly impair the mechanical properties, in particular the bending strength of the parts.
- the powder can be produced using all suitable processes, in particular using gas atomization processes, after which, if appropriate, compacting is carried out by hot-isostatic pressing and / or by hot-working the powder in suitable casings.
- the wear behavior of the part was tested in the grinding wheel test, in which a steel disc rotates in a corundum-water mixture, against which the sample is pressed.
