Incoloy 020 Alloy Steel Bar
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 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.
Incoloy®Alloy 20(UNS N08020) is an austenitic nickel-iron-chromium alloy with additions of copper and molybdenum. The nickel content makes Alloy 20 resistant to chloride-ion stress-corrosion cracking. Copper and molybdenum give resistance to reducing environments. The molybdenum content also provides good resistance to pitting and crevice corrosion. The chromium gives resistance to oxidizing environments such as nitric acid. The addition of niobium reduces the effect of carbide precipitation during welding, thus increasing the alloy’s resistance to intergranular corrosion.
Alloy 20 has exceptional corrosion resistance in sulfuric acid environments, and is used in a range of applications involving this acid. Other uses include the production of gasoline, solvents, explosives, inorganic and organic chemicals, pharmaceuticals, food and synthetic materials. For these and other applications, Alloy 20 is readily fabricated to produce mixing tanks, heat exchangers, process piping, pickling equipment, pumps, valves, fasteners and fittings.
Hot forming should be in the range 1400-2150°F (760- 1175°C). Incoloy® alloy 20 is normally used in the annealed condition. Annealing: 1800-1850°F (982- 1010°C)/ for a time commensurate with section size/AC.
Incoloy® alloy 20 is designated as UNS N08020. Standard product forms include pipe, tube, sheet, strip, plate, round bar, flat bar, forging stock, hexagon and wire. Rod, Bar, Wire and Forging Stock.
