INCOLOY is an alloy composed of nickel-iron-chromium, with additions of molybdenum and copper. These alloys are categorized as super alloys and exhibit excellent corrosion resistance and high strength. Some of the INCOLOY alloys are specifically made to resist selected reagents. These alloys are capable of functioning even at high temperatures.

INCOLOY alloy 020 exhibits excellent corrosion resistance in chemical environments that contain sulphuric acid, chlorides, phosphoric acid and nitric acid. It is easy to fabricate this alloy to form mixing tanks, heat exchangers, pickling equipment etc. The standard forms in which this alloy is available are round, flats, pipe, tube, strip and wire.

This datasheet will look into the chemical composition, properties and applications of INCOLOY 020.

INCOLOY alloy 020 can be welded by shielded metal arc welding, gas tungsten arc welding and gas metal arc welding. The filler metal is usually an INCONEL alloy.

Hot Working

INCOLOY alloy 020 can be hot worked at temperature ranges of 760-1175°C (1400-2150°F).


INCOLOY alloy 020 should be annealed at 982-1010°C (1800-1850°F) for time commensurate with section size /AC.


The INCOLOY alloy 020 is used in the following applications:

  • Produce mixing tanks, heat exchangers, valves, fittings and fasteners
  • Production of gasoline, solvents, explosives and organic chemicals
  • Pharmaceuticals and food industry
