Definitions
- the invention relates to a metallic material with resistance in medium-concentrated sulfuric acid and hydrochloric acid solutions at high temperatures.
- Sulfuric acid is one of the most important raw materials in the chemical industry. Sulfuric acid has a wide range of applications in the chemical industry, using it at different temperatures and in different concentrations. For the metallic materials used for their handling that has a different corrosive stress result. This usually increases with the temperature until finally no corrosion resistance is given. The respective upper limit of application is shown in so-called isocorrosion diagrams as a function of the concentration of sulfuric acid.
- FIG. 1 shows by way of example such an isocorrosion diagram, including the comparative illustration of the stability of various known metallic materials in pure sulfuric acid (Metals Handbook, 9th Edition, Vol. 13: Corrosion, ASM International, Metals Park, Ohio 44073, 1987).
- Methods Handbook, 9th Edition, Vol. 13: Corrosion, ASM International, Metals Park, Ohio 44073, 1987 As a measure of the resistance, the 0.5 mm / year isosorrosion lines for different known metallic materials are shown there. In the present case, below these lines, by definition, are the resistance ranges of the respectively associated materials. It can be seen in FIG. 1 that the resistance range of the stainless steel marked with type 316 initially decreases considerably with increasing concentration of the sulfuric acid, and then finally spreads again to higher temperatures as the concentration increases further.
- nickel-molybdenum alloys B / B-2 have sufficient corrosion resistance within a broader concentration interval of the sulfuric acid.
- the disadvantages of these nickel-molybdenum alloys B / B-2 according to the prior art are, above all, the high raw material costs and thus high metal values for their alloying elements, which consist very largely of nickel and molybdenum.
- the alloy B-2 which is largely customary today, is made according to UNS (Unified Numbering System) N 10665 or EN (European Standard) 2.4617 (in% by mass) 26 to 30% molybdenum, max. 2% iron, max. 1% chromium, max. 1% manganese, max. 0.08% Si and max. 0.01% carbon, balance essentially nickel together.
- alloys such as B-3 have been tried to reduce the alloy contents of the less expensive alloying elements iron, chromium and manganese to (in% by mass) 1 to 3% iron, 1 to 3% chromium and Max. 3% manganese, with an exemplary nickel content of 68% by mass is given (see High-alloyed materials, corrosion behavior and application, TAW - Verlag, Wuppertal 2002, p 192).
- an iron content of 4 to 6% by mass is stated according to UNS N10001.
- DE 42 10 997 relates to an austenitic nickel-molybdenum alloy of the following composition (in% by mass): Mo 26-30%; Fe 1 - 7%, Cr 0.4 - 1, 5%, Mn up to 1, 5%, Si up to 0.05%, Co up to 2.5%, P up to 0.04%, S up to 0.01% , Al 0.1-0.5%, Mg to 0.1%, Cu to 1, 0%, C to 0.01%, N to 0.01%, remainder Fe.
- Mo 26-30% Mo 26-30%
- the present invention has for its object to find a metallic material that is resistant in 20 to 80% sulfuric acid at high temperatures up to 13O 0 C, which at the same time has sufficient resistance cooling water side, and especially in the metal value in comparison is significantly reduced to the usual according to the prior art metallic alloys.
- An advantageous alloy consists of (in% by mass)
- Another preferred alloy consists of (in% by mass) Ni 61, 5 - 62.5%
- the alloy according to the invention can be used for components with high corrosion resistance to reducing media, in particular hot medium-concentrated sulfuric acid and hydrochloric acid solutions.
- the preferred field of application of the alloy according to the invention is seen in the field of chemical plants, since larger applications for reducing media at higher temperatures are seen here.
- the alloy as a wire-like trained same-like filler and / or for welding nickel-molybdenum alloys.
- the alloy according to the invention can be used, for example, as a kneading material for the production of metal sheets, strips, wires, rods, forgings and pipes and as castings.
- the disadvantageous state of the art characterized by the high metal values of nickel and molybdenum can be perceptibly softened if a previously mentioned nickel-molybdenum-iron alloy is used for the handling of the hot sulfuric acid.
- the average content of nickel is advantageously between 61 and 63% by mass. This means a reduction by 6 to 7% by mass of the costly alloying element nickel compared to the prior art outlined by way of example at the outset.
- the content of the equally costly alloying element molybdenum is between 24 and 26 mass% on average well below that for the nickel-molybdenum alloys exemplified with 27 and 28% by mass of molybdenum prior art (see., High-alloyed materials, corrosion behavior and Application, TAW - Verlag, Wuppertal 2002, p. 192).
- Table 1 Chemical composition of the investigated nickel-molybdenum-iron alloys in spectral analytical determination in comparison to a nickel-molybdenum alloy B-2 according to the prior art according to the literature (see High-alloyed materials, corrosion behavior and application, TAW - Verlag, Wuppertal 2002, p. 192).
- Table 1 shows nickel-molybdenum-iron alloys according to the invention in comparison with nickel-molybdenum-iron alloys outside the invention and the prior art nickel-molybdenum alloy B-2. Some admixtures and impurities due to melting are not listed.
- iron contents between 11 and 12% by weight and in one case an iron content of 14.7% by mass were tested, compared to the exemplary iron content of only 1.7% by weight, that for alloy B-2 according to the prior art.
- the tested molybdenum contents are between 20.4 and 25.6 mass% compared to the exemplary molybdenum content of 28 mass% reported for the prior art alloy B-2.
- the proven nickel contents are between 60.1 and 63.3% by mass, as compared to the exemplary 69% by weight nickel content given for the prior art alloy B-2.
- Table 2 shows the corrosion erosions of the alloys indicated in Table 1.
- Table 2 Corrosion erosion of the inventive embodiments 50 and 44 of the examined nickel-molybdenum-iron alloy in hot medium concentrated sulfuric acid compared to two outside the invention lying nickel molybdenum-iron alloys 51 and 45 and compared to the one of the prior Technique corresponding nickel-molybdenum alloy B-2.
- Table 2 shows the corrosion erosion of embodiments 50 and 44 according to the invention of the examined nickel-molybdenum-iron alloy in hot medium-concentrated sulfuric acid in comparison with two non-inventive nickel-molybdenum-iron alloys 51 and 45 and in comparison with the prior art Technique associated nickel-molybdenum alloy B-2.
- the corrosion erosion of the embodiments 50 and 44 according to the invention is up to those of the inventive embodiment 50 in 80% HaSO 4 at 13O 0 C below the 0.5 mm / a isosorrosion line of Figure 1.
- the corrosion resistance of the welds of Embodiment 50 of the examined nickel-molybdenum-iron alloys in hot medium concentrated sulfuric acid (30 and 50%) is similar to that of the unwelded state.
- the inventive embodiment 50 of the investigated nickel-molybdenum iron alloys showed immersion test in 4% strength sodium chloride solution at 150 0 C for 120 hours, a corrosion rate of 0.08 mm / a. This means cool water side sufficient resistance even in heavily contaminated with chloride cooling water according to the task.
- the mechanical properties of the inventive design 44 of the tested nickel-molybdenum-iron alloys determined in the tensile test at room temperature were Rp o , 2 ⁇ 350 N / mm 2 , Rp 1 , 0 ⁇ 380 N / mm 2 , Rm> 760 N / mm 2 and A5 ⁇ 40% comparable to those of the prior art nickel-molybdenum alloy B-2 (compare Sheet and Plate - High Performance Materials: Publication N ° N 554 98-10 of Krupp VDM GmbH, p. 34/35), whereas the embodiment 45 of the investigated nickel-molybdenum-iron alloys outside the invention did not reach the stated strength values.
