Characteristics

Corrosion resistance in an extensive range of marine and chemical environments. From pure water to nonoxidizing mineral acids, salts and alkalis.This alloy is more resistant to nickel under reducing conditions and more resistant than copper under oxidizing conditions, it does show however better resistance to reducing media than oxidizing.Good mechanical properties from subzero temperatures up to about 480C.Good resistance to sulfuric and hydrofluoric acids. Aeration however will result in increased corrosion rates. May be used to handle hydrochloric acid, but the presence of oxidizing salts will greatly accelerate corrosive attack.Resistance to neutral, alkaline and acid salts is shown, but poor resistance is found with oxidizing acid salts such as ferric chloride.Excellent resistance to chloride ion stress corrosion cracking.

Applications

Feed water and steam generator tubing.Brine heaters, sea water scrubbers in tanker inert gas systems.Sulfuric acid and hydrofluoric acid alkylation plants.Pickling bat heating coils.Heat exchangers in a variety of industries.Transfer piping from oil refinery crude columns.Plant for the refining of uranium and isotope separation in the production of nuclear fuel.Pumps and valves used in the manufacture of perchlorethylene, chlorinated plastics.Monoethanolamine (MEA) reboiling tube.Cladding for the upper areas of oil refinery crude columns.Propeller and pump shafts.
