Abstract (en)
[origin: WO2013182178A1] The invention relates to a nickel-chromium alloy comprising (in wt.-%) 29 to 37% chromium, 0.001 to 1.8% aluminum, 0.10 to 7.0% iron, 0.001 to 0.50% silicon, 0.005 to 2.0% manganese, 0.00 to 1.00% titanium and/or 0.00 to 1.10% niobium, 0.0002 to 0.05% each of magnesium and/or calcium, 0.005 to 12% carbon, 0.001 to 0.050% nitrogen, 0.001 to 0.030% phosphorus, 0.0001 to 0.020% oxygen, not more than 0.010% sulfur, not more than 2.0% molybdenum, not more than 2.0% tungsten, the remainder nickel and the usual process-related impurities, wherein the following relations must be satisfied: Cr + Al >= 30 (2a) and Fp <= 39.9 (3a) with Fp = Cr + 0.272*Fe + 2.36*Al + 2.22*Si + 2.48*Ti + 0.374*Mo + 0,538*W - 11.8*C (4a), wherein Cr, Fe, Al, Si, Ti, Mo, W and C is the concentration of the respective elements in % by mass.
