Alloy 20, is a low-carbon, niobium-stabilized austenitic nickel/iron/chromium alloy with additions of molybdenum and copper that was developed for maximum resistance to acid attack, specifically sulfuric acid also known as Carpenter 20. It is also stabilized with Columbium to minimize carbide precipitation during welding. Carpenter 20 contains niobium for stabilization against sensitization and resultant intergranular corrosion. Alloy 20 combines elevated mechanical properties, relatively easy fabrication along with excellent corrosion resistance. Alloy 20 has various characteristic features like excellent general corrosion resistance to sulfuric acid, excellent resistance to chloride stress corrosion cracking, excellent mechanical properties and fabricability, minimal carbide precipitation during welding, excels in resisting corrosion to hot sulfuric acids. 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 various applications like synthetic rubber manufacturing equipment, processing of pharmaceuticals, plastics and organic and heavy chemicals, petrochemical process equipment, tanks, piping, heat exchangers, pumps, valves, and other process equipment, acid cleaning and pickling equipment, chemical process piping, reactor vessels, bubble caps, food and dye production, etc.
