Incoloy 20 contains niobium for stabilization which enhances its corrosion resistance. The alloy is an iron-base, austenitic alloy with excellent corrosion resistance to a wide range of media.
Alloy 20 shows good resistance to chloride-induced stress corrosion cracking on high nickel content. In addition the alloy also has good resistance to pitting and crevice corrosion.
In the chemical process market, key applications of Alloy 20 are in sulphuric, phosphoric and nitric acid environments.
The alloy is also commonly used in the food industry for the manufacture of food preservatives (phosphorus oxychloride and phosphorus trichloride).
Other uses include the production of gasoline, solvents, explosives, inorganic and organic chemicals, pharmaceuticals, and food and synthetic materials. INCOLOY alloy 020 is readily fabricated to produce mixing tanks, heat exchangers, process piping, pickling equipment, pumps, valves, fasteners and fittings. Applications for alloy 020 requiring resistance to aqueous corrosion are essentially the same as those for INCOLOY alloy 825.
Common Trade Names:
Alloy 20 / Incoloy 20 / Carpenter 20 / UNS: N08020 / W. Nr: 2.4660
Specifications：

Incoloy 20 Characteristic:
Excellent corrosion resistance and can be used in chloride ion environment. Technical parameters are: hydrochloric acid resistance concentration 0-80%, temperature less than or equal to 65℃; Sulfuric acid resistance concentration 0-33%, temperature less than or equal to 100℃; Resistance to hydrofluoric acid concentration 0-85%, temperature less than or equal to 60℃.
It can still maintain good corrosion resistance in high temperature environment.
Excellent resistance to wear, especially at high temperature and pressure.
With high strength, ductility and impact toughness and other mechanical characteristics, can meet various engineering needs.
In the process of welding performance is good, in the correct selection of welding materials and welding technology, can achieve high quality welding.
It shows good stability in high temperature environment without deformation or failure.
