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.

A homogenizaton heat treatment for enhancing crevice and pitting corrosion resistance minimizes the formation of Mu phase in nickel-base alloys of high combined percentages of chromium, e. g. , 19 to 23% and molybdenum, e. g. , 14 to 17%, particularly together with tungsten. Also described is an advantageous alloy composition containing less than 2. 5% iron, low carbon and a titanium to carbon ratio greater than 1 which is particularly adapted to be effectively treated by the homogenization heat treatment.

Iron-based alloy composition containing special proportions of nickel, chromium, aluminum, copper and carbon provides good corrosion-resistance characteristics for service in caustic media, e. g. , sodium hydroxide, chloride media, e. g. , magnesium chloride, caustic-chloride media, e. g. , sodium hydroxide-sodium chloride mixtures, and also when exposed to some acid media, e. g. , nitric acid. Special utility particularly includes resistance to stress-corrosion-cracking in hot caustic and chloride media. Alloy has good workability for production of wrought products such as plate, bar and sheet and is also suitable for making corrosion-resistant castings and welded structures, e. g. , chemical plant equipment.

A nickel-base alloy having characteristics midway between selected stainless steels and INCONEL. RTM. alloy 625LCF. RTM. Flexible and particularly useful for exhaust system bellows, wires and braids, the alloy includes about 24-42% nickel, about 18-28% chromium, 1. 5-6% molybdenum, 0. 2-1 % titanium, up to 1% aluminum, the balance iron, and up to about 1. 4% silicon. The alloy demonstrates a novel characteristic of becoming stronger and more ductile during contemplated service temperatures of about 800. degree. -1400. degree. F. (427. degree. C. -760. degree. C. ).
