Alloy 20 N08020 Seamless Pipe with excellent corrosion resistance Small MOQ fast delivery

UNS N08020, also known as Carpenter® 20, 20Cb-3, is a nickel-iron-chromium austenitic alloy that was developed for maximum resistance to acid attack, specifically sulfuric acid.

UNS N08020 has excellent corrosion resistance in chemical environments containing sulfuric acid, and useful resistance to environments containing chlorides, nitric acid, and phosphoric acid. Other uses include the production of gasoline, solvents, explosives, inorganic and organic chemicals, and food and synthetic materials. It is readily fabricated to produce mixing tanks, heat exchangers, process piping, pickling equipment, pumps, valves, fasteners and fittings.
