<p>A hardenable nickel alloy has a yield strength of at least 500 N/mm2 and a high corrosion resistance in very aggressive acid gas media. The alloy consists of 43 to 51 % nickel, 19 to 24 % chromium, 4.5 to 7.5 % molybdenum, 0.4 to 2.5 % copper, 0.3 to 1.8 % aluminium and 0.9 to 2.2 % titanium, the remainder being iron. Also described are processes for heat-treatment of the alloy which ensure high strength together with good ductility.</p> |
