Nickel alloy 20 is a low-carbon, niobium-stabilized austenitic nickel/iron/chromium alloy with additions of molybdenum and copper. It exhibits exceptional corrosion resistance in chemical environments containing phosphoric acid, nitric acid, chlorides, and sulfuric acid. It also has good mechanical properties at both ambient and elevated temperatures. Alloy-20 is used in a variety of industries, including chemical processing, petrochemical and refining, marine, pharmaceutical, and food processing. End-use applications include storage tanks, mixing tanks, agitators, pump and valve parts, food processing equipment, fasteners, and fittings. Alloy 20 has a very good resistance to sulfuric acid. This alloy also shows suitable resistance in phosphoric acid, nitric acid, and aqueous salt solutions. Alloy 20 asme is an excellent option when chloride stress corrosion cracking is an issue, as it resists pitting and crevice corrosion. Caution should be taken in chloride ion-containing environments because the corrosion rate can increase significantly. Inconel 600 data-sheet can be formed by either hot-working or cold-work using traditional methods. Hot forged material should be heated between 2100°F and 2250°F with careful temperature control ensuring that the material does not fall below 1800°F prior to forging. After hot working, anneal the material by heating to 1725°F and 1850°F for a minimum of 30 minutes per inch of thickness followed by water quench.
This Alloy 20 Scrap can be used for manufacturing high-quality efficient alloy 20 steel products for Synthetic rubber manufacturing equipment, Processing of pharmaceuticals, plastics, and organic and heavy chemicals, Tanks, piping, heat exchangers, pumps, valves, and other process equipment, Acid cleaning and pickling equipment, Chemical process piping, reactor vessels, Bubble caps, Petrochemical process equipment, Food, and dye production.
