Definitions

  • the invention relates to an alloy according to claim 1 and the uses according to claims 2 to 11.
  • Hydrochloric acid is the only mineral acid that is compatible with the human and animal body.
  • the new material requirement is that of particularly high resistance to dilute hydrochloric acid.
  • this alloy has a significantly better corrosion resistance under all test conditions than corresponds to the state of the art (stdT) according to DE-OS 31 25 301.
  • the test results were obtained on four working examples Nos. 1 to 4 of the alloy according to the invention, the chemical analyzes of which are listed in Table 1.
  • Table 1 also contains the analyzes of comparative samples Nos. 5 and 6 corresponding to the state of the art according to DE-OS 31 25 301, which have already been produced in accordance with this invention with regard to the levels of deoxidation elements aluminum, magnesium and calcium which determine their processability were.
  • a boiling aqueous solution with 23% H2SO4, 1.2% HCl, 1% FeCl3 and 1% CuCl2 according to ASTM G-28, Method B can be used as a test solution for the tasks of thin acid concentration.
  • Table 2 makes clear, the alloy according to the invention has a 30% lower removal rate there than corresponds to the older prior art. Are not the own measurements for the prior art (comparative sample 6 in Table 2), but the specification of 0.17 mm / year in "Materials and Corrosion", Volume 37 (1986), pp. 137-145, the alloy according to the invention is even 59% above the prior art.
  • the alloy according to the invention shown in Table 3 is essentially the same as the prior art.
  • the critical pitting corrosion temperature determined for the prior art corresponds to the information in "Materials and Corrosion", Volume 37 (1986), pp. 137-145.
  • the alloy according to the invention here has only a slight tendency to be superior, as the measurement results in working examples 3 and 4 show.
  • the identical values for the local corrosion resistance in the known 10% FeCl3 ⁇ 6H2O solution given in the same table for the prior art and the invention are only identical because the test conditions do not allow measurements at a higher temperature.
  • Table 4 shows the clear superiority of the alloy according to the invention over the prior art with regard to the susceptibility to crevice corrosion in the same solution at 85 ° C., measured with a conventional crevice block arrangement made of PTFE (cf. "Materials and Corrosion", volume 37 ( 1986), p. 185).
  • the increased resistance of the alloy according to the invention to local corrosion comes, of great importance.
  • the alloy according to the invention can thus be used where the alloy corresponding to the prior art can no longer be used due to local corrosion, for example in prewashers with particularly aggressive working conditions.
  • Table 5 also gives the linear removal rates in typical flue gas desulfurization media.
  • the far better suitability of the alloy according to the invention is evident, especially in the case of the dilute 2% sulfuric acid solution at high temperature (105 ° C.) and with a high chloride content, where the average removal rate is around 93% lower than that of the Alloy corresponding to the state of the art.
  • the higher resistance of the alloy according to the invention in dilute hydrochloric acid compared to the prior art is shown in Table 6. Accordingly, the alloy according to the invention behaves about 60% better in this reducing acid than the comparative samples corresponding to the prior art. Significant progress of around 25% is still given if the comparison shows the removal rate of 0 published elsewhere ("Materials and Corrosion", Volume 37 (1986), pp. 137-144) for the state of the art , 28 mm / year. Table 6 also gives information on the resistance in chloride-free 10% H2SO4 as another important reducing acid. The removal rate there is reduced by around 64% compared to the prior art and still by 50% if the comparison for the prior art is based on the information in DE-OS 31 25 301 of 0.36 mm / year.
