ABSTRACT:
A nickel-based alloy which is excellent not only in anti-corrosion properties but also in workability is disclosed. The alloy contains 15 to 35 weight % of chromium; 6 to 24 weight % of molybdenum; wherein the sum of chromium plus molybdenum is no greater than 43 weight %; 1.1 to 8 weight % of tantalum; and balance nickel and unavoidable impurities. The alloy may optionally include no greater than 0.1 weight % of nitrogen; no greater than 0.3 weight % of magnesium, no greater than 3 weight % of manganese, no greater than 0.3 weight % of silicon, no greater than 0.1 weight % of carbon, no greater than 6 weight % of iron, no greater than 0.1 weight % of zirconium, no greater than 0.01 weight % of calcium, no greater than 1 weight % of niobium, no greater than 4 weight % of tungsten, no greater than 4 weight % of copper, no greater than 0.8 weight % of titanium, no greater than 0.8 weight % of aluminum, no greater than 5 weight % of cobalt, no greater than 0.5 weight % of vanadium, no greater than 2 weight % of hafnium, no greater than 3 weight % of rhenium, no greater than 1 weight % of osmium, no greater than 1 weight % of platinum, no greater than 1 weight % of ruthenium, no greater than 1 weight % of palladium, no greater than 0.1 weight % of lanthanum, no greater than 0.1 weight % of cerium, or no greater than 0.1 weight % of yttrium.
