HASTELLOY C276 :
Alloy 20 is a nickel-iron-chromium alloy with some amounts of copper and molybdenum. The nickel in this alloy makes it resistant to chloride-ion stress-corrosion cracking. On the other hand, copper and molybdenum make it resistant to reducing environments and also provide good resistance to pitting and crevice corrosion. The chromium makes it suitable for work with chemicals like nitric acid, by adding resistance to oxidizing environments. The molybdenum, is also essential for this alloy as it helps to reduce the effect of carbide precipitation during welding and thereby increasing alloy's resistance to intergranular corrosion. 

INCO alloy 20 is extremely resistant to corrosion in sulfuric acid environments and hence finds utility with this acid as well as in production of gasoline, solvents, explosives, inorganic and organic chemicals etc. In case of other application, INCO alloy 020 is easily prepared to produce mixing tanks, heat exchangers, process piping, pickling equipment, pumps, valves, fasteners and fittings.
