Definitions
- Martensitic, corrosion-resistant tool steels are used for the production of tools which are exposed to corrosive media in practice and which are subject to high demands on their hardness.
- Machining processes are an essential part of industrial production technology and a main cost when manufacturing tools for plastics processing.
- the economic usability of steels of the type mentioned above depends essentially on their machinability and their corrosion resistance, which in turn is decisively influenced by the chromium content of the steels.
- machinability means the property of a material that can be machined under certain conditions.
- a stainless martensitic steel with good machinability is known from EP 0 721 513 B1.
- the known steel contains 10 to 14 mass% chromium. To improve its machinability, it also has at least 0.15% sulfur and 1.0 to 3.5% copper. The addition of copper also has a positive influence on the hardness of the alloy.
- chromium-alloyed, corrosion-resistant steels are known, the chromium content of which is between 11.0 and 17.0 mass%. These are, for example, the steels designated with the material numbers 1.2080, 1.2082, 1.2083, 1.2085, 1.2201, 1.2314, 1.2316, 1.2319, 1.2361, 1.2376, 1.2378, 1.2379, 1.2380, 1.2436, 1.2601 in the StahlEisen list. These steels are regularly alloyed with carbon, silicon and manganese. They also optionally contain carbide formers such as molybdenum, vanadium or tungsten.
- the known steels are processed depending on the respective carbon and carbide content.
- the steels of the type in question are used on the one hand by the tool manufacturer in a tempered state with a hardness of 285 to 325 HB. With this hardness, machining of the material is still possible.
- the steels are processed in the soft annealed condition, the hardness of the steels then being a maximum of 250 HB. Such less hard steels can be processed better.
- a heat treatment must still be carried out after processing in order to achieve the usually required Achieve hardness of 46 to 60 HRC. Finishing is then required.
- the object of the invention is to find a steel which is particularly suitable for the production of tools for the plastics processing industry and which, with high hardness and corrosion resistance, has toughness, machinability and weldability which meet the practical requirements.
- a method for producing intermediate products from such a steel is to be specified.
- intermediate product is also understood to mean long products, flat products or other objects which are subsequently sent for further processing.
- P at most 0.035%
- S at least 0.04% and less than 0.15%
- Cr more than 8.0% and less than 12%
- Mo more than 0.0% and at most 0.20%
- V more than 0, 0% and at most 0.25%
- Nb more than 0.1% and at most 0.5%
- N at least 0.02 and at most 0.12%
- Ni at most 0.5%
- B at most 0.005%
- Cu 0.3% or less
- AI 0.035% or less
- Sn 0.035% or less
- the nioballoyed tool steel according to the invention has an optimized combination of machinability, hardness, corrosion resistance, weldability and toughness. It reaches hardness layers that are between 300 and 450 HB. Despite the relatively high sulfur content, it has good toughness for steels of the generic type, which meets the requirements that arise in practice.
- steels according to the invention are sulfur-alloyed, the proportion of each of which is less than 0.15% by mass.
- the steel preferably has at least 0.04% by mass, whereby good machinability can be reliably ensured. Yet Better machinability can be achieved when the other conditions imposed on the composition are taken into account if the steel according to the invention contains at least 0.07% by mass of sulfur.
- steel according to the invention has good toughness. This is achieved in that the steel together with the sulfur contains at least one of the elements calcium, manganese or cerium in amounts, the sum of which is more than 0.0002 but at most 0.015 mass%. These elements enable sulfides to be molded into the matrix of the steel and thus improve its toughness. This can be achieved with certainty, for example, if the steel according to the invention contains 0.001-0.009% by mass of calcium.
- the respective Nb content of the steel is designated with% Nb.
- the carbon and nitrogen present are largely bound to hard phases by the niobium element, so that the chromium contained in the matrix according to the invention with a content of less than 12% is fully available for the formation of corrosion-inhibiting passive layers.
- steel according to the invention has excellent corrosion resistance despite the relatively low chromium contents and high hardness.
- the embrittlement factor KG f fulfills the following condition, the negative influence of the elements which act on the grain boundaries and the associated risk of crack formation can be minimized in a targeted manner:
- the above-mentioned object is achieved by performing at least the following production steps:
- Casting the steel into a starting material such as blocks, slabs, continuous cast bars, thin slabs or cast strip,
- the diffusion annealing of the primary material carried out in the temperature range selected according to the invention compensates for the segregation-related segregations, so that a uniform distribution of the alloy elements contained is achieved.
- the structure and the material isotropy are influenced.
- An improved structure of the structure and a higher isotropy of the material can be achieved in that the hot deformation is carried out using a degree of deformation ⁇ of at least 1.5.
- hot forming can be carried out as forging or, for the production of larger dimensions, as hot rolling.
- Hot forming preferably takes place at temperatures of 850 ° C - 1100 ° C. In this temperature range, the material used according to the invention has a low yield stress and a high toughness, so that there is an optimal formability. Hot forming can thus be carried out quickly, inexpensively and with a high output.
- the workpiece produced according to the invention is preferably placed in air after the hot forming from the forming heat.
- the material When stored in air, the material is slowly and completely converted from the austenitic to the martensitic state.
- Such slow cooling sets the desired hardness of the material of up to 450 HB.
- thermal and transformation stresses are largely avoided, so that there are no distortions or stress cracks in the finished intermediate product.
- a hardness of the intermediate product produced can be produced which differs from the hardness present after being stored in air from the heat of deformation.
- this heat treatment can also achieve lower hardness values down to a lower limit of 300 HB.
- Diag. 2 the impact bending work determined for various steels plotted against the embrittlement factor KG f .
- Table 1 compares the alloys of steels A, B, C according to the invention with the compositions of four comparative steels D, E, F, G lying outside the invention.
- Table 2 also shows the Brinell hardness values belonging to steels A to G as well as the hardness (H f ), sweat (S f ) and embrittlement factors (KG f ).
- the test was carried out at room temperature. Like the one in Diag. 2 summarized values for the impact bending work (mean values from 3 tested individual samples) show, with increasing embrittlement factor KG f a significant decrease in the measured impact bending work can be determined.
- the steels A, B and C according to the invention have the desired high level of toughness with values well above 200 J, while only values between 50 and 150 J could be measured for the steels D, E, F and G with increasing embrittlement factor, their toughness was therefore significantly lower.
- Comparable has been found in connection with the value to be observed for the weldability factor S f of steels according to the invention.
- the comparative steels, the welding factor S f of which are above the limit value provided according to the invention, have a significantly poorer welding behavior than the steels according to the invention. This is particularly evident in the occurrence of welding cracks, to avoid which, in the case of the steels not according to the invention, complex preheating and post-treatment are necessary.
- the examples show that the inventive limitation of the contents of elements with a grain-boundary effect, such as Cu, Sn, As, AI, P and N, in the case of steels A, B, C keeps the respective embrittlement factor KG f low and, consequently, one for steels good toughness has been achieved.
