Definitions
- the invention relates to a heat-resistant, thermoformable, austenitic nickel alloy and its use as a material for heat and corrosion-resistant objects.
- the nickel alloy with the material Mr. 2.4856 was used according to the steel iron list of the Association of German Ironworkers. It consists of (in% by weight) max. 0.10% carbon, max. 0.5% silicon, max. 0.5% manganese, 20-23% chromium, 8-10% molybdenum, 3.15-4.15% niobium, max. 0.4% titanium, max. 0.4% aluminum, balance nickel.
- this standard alloy shows strong carburizing phenomena under strong carburizing conditions at temperatures above 900 ° C, which are expressed in a significant weight gain through strong carbide deposits and carbon absorption. As a result, the mechanical properties, in particular the long-term strength, are additionally adversely affected. Even under oxidizing / sulfidizing conditions such as in a gas atmosphere made of nitrogen and 10% SO2 at 750 ° C, the standard alloy shows significant damage due to sulfur absorption.
- the austenitic steel known from EP-PS 0 135 321 (data in% by weight) with max. 0.03% carbon, 20-35% chromium, 17-50% nickel and 2-6% silicon is resistant to, due to its high Si content
- Corrosion in strongly oxidizing mineral acids, such as nitric acid, is not suitable for use at temperatures above 500 ° C under carburizing, sulfidizing and oxidizing conditions.
- nickel-chromium alloys which have nickel or nickel + cobalt as a base and with 5-45% Cr, no more than 1% C, no more than 5% Ti, no more than 5% Si and not more than 1% N, Mg, Cu, Ca or rare earth metals are alloyed.
- nickel alloys are also known, the 10-40% Co, 10-30% Cr, 2-18% Mo, 0.2-8.6% Al and 0.2-4.4% Ti contain. Forged turbine blades, in particular, are produced from the nickel alloys.
- an austenitic nickel alloy consisting of (data in% by weight) carbon 0.05 to 0.15 silicon 2.5 to 3.0 manganese 0.2 to 0.5 phosphorus Max. 0.015 sulfur Max. 0.005 chrome 25 to 30 iron 20 to 27 aluminum 0.05 to 0.15 Calcium 0.001 to 0.005 Rare earth 0.05 to 0.15 nitrogen 0.05 to 0.20
- the alloy according to the invention is advantageously suitable as a material for the production of objects which have to be resistant to carburization, sulfidation and oxidation at temperatures in the range from 500 to 1000 ° C., in particular in the case of cyclic loading. It is preferably used as a material for the production of plants for thermal waste disposal or for coal gasification and parts thereof. In particular when it comes to waste disposal in incineration plants, the furnace parts are subjected to high cyclical stresses due to changing temperatures during heating and cooling as well as fluctuations in the exhaust gas composition.
- the alloy according to the invention can be used without restriction as a material for the production of thermally stressed furnace built-in parts, such as support frames for furnaces, transport rails and conveyor belts be used.
- Table 1 The actual analyzes of the comparative alloys A and B are listed in Table 1 (data in% by weight) Table 1 Leg. A Leg. B carbon 0.086 0.021 silicon 2.76 0.15 manganese 0.29 0.17 phosphorus 0.011 0.007 sulfur 0.003 0.004 chrome 27.0 22.20 iron 23.3 2.71 aluminum 0.12 0.13 Calcium 0.003 0.003 Rare earth 0.058 --- nitrogen 0.08 0.02 nickel 46.25 63 niobium --- 2.4 molybdenum --- 9.1
- Figure 1 shows the carburizing behavior of the leg. A compared to Leg. B.
- the specific mass change in g / m2 over time in hours is shown here.
- the test temperature was 1000 ° C.
- the test was carried out cyclically, ie with a cycle time of 24 hours, the holding time at test temperature was 16 hours with a total of 8 hours heating up and cooling down.
- the Leg according to the invention. A is characterized by a significantly smaller increase in mass compared to the comparative alloy B.
- Figure 2 This representation corresponds in execution and test execution of the representation in Fig. 1. Only the test medium was nitrogen + 10% SO2 at 750 ° C in this case to test the sulfidation resistance. Leg is superior in this test as well. A versus Leg. B with respect to the mass change.
- Figure 3 describes the cyclic oxidation behavior of the comparison materials A and B in air at 1000 ° C.
- the test conditions and the presentation of the results correspond to FIG. 1.
