Abstract (en)
[origin: WO2021110218A1] The invention relates to a nickel-chromium-aluminum alloy comprising (in mass %) 12 to 30% chromium, 1.8 to 4.0% aluminum, 0.1 to 7.0% iron, 0.001 to 0.50% silicon, 0.001 to 2.0% manganese, 0.00 to 1.00% titanium, 0.00 to 1.10% niobium, 0.00 to 0.5% copper, 0.00 to 5.00% cobalt, in each case 0.0002 to 0.05% magnesium and/or calcium, 0.001 to 0.12% carbon, 0.001 to 0.050% nitrogen, 0.001 to 0.030% phosphorus, 0.0001 to 0.020% oxygen, max. 0.010% sulfur, max. 2.0% molybdenum, max. 2.0% tungsten, and a remainder of nickel with a minimum content of ≥ 50% and the usual process-related impurities for use in solar power towers, using chloride and/or carbonate salt melts as a heat transfer medium, wherein in order to ensure a good processability, the following condition must be met: Fv ≥ 0.9 mit Fv = 4.88050 - 0.095546*Fe - 0.0178784*Cr - 0.992452*AI - 1.51498*Ti - 0.506893*Nb + 0.0426004*AI*Fe, where Fe, Cr, AI, Ti, and Nb are the concentration of the respective elements in mass %.
