- Nickel Alloy 20 stud Bolt (UNS N08020) is a low-carbon, niobium-stabilized austenitic Nickel/iron/chromium alloy with additions of copper and molybdenum. It has excellent corrosion resistance in chemical environments containing sulfuric acid, and resists
environments containing chlorides, nitric acid, and phosphoric acid. It is well suited to the production of gasoline, solvents, explosives, inorganic and organic chemicals, pharmaceuticals, food, and synthetic materials.And it is ideal for applications such as the production of mixing tanks, heat exchangers, process piping, pickling equipment, pumps, valves, fasteners and fittings.
