Abstract
A nickel-chromium-molybdenum-niobium alloy affords high resistance to aggressive corrosives, including chlorides which cause crevice corrosion and oxidizing acids which promote intergranular corrosion, the alloy also being readily weldable and possessing structural stability at very low as well as elevated temperatures. The alloy consists essentially of, (by weight), 19-23% Cr, 12-15% Mo, 2.25-4% W, 0.65-2% Nb, 2-8% Fe, balance Ni.
