ASTM B463 UNS N08020 Sheet, 2.4660 Alloy 20 Plate, Alloy 20 Stainless Steel Strip, Alloy 20 Sheet Suppliers, Alloy 20 Steel Coil, UNS N08020 Coil.

Alloy 20, also known as Carpenter 20, is a nickel-iron-chromium austenitic alloy that was developed for maximum resistance to acid attack, specifically sulfuric acid. Alloy 20 Plate has excellent resistance to general corrosion, pitting, and crevice corrosion in chemicals containing chlorides and sulfuric, phosphoric, and nitric acids. ASTM B463 UNS N08020 Sheet also contains niobium for stabilization against sensitization and resultant intergranular corrosion. 

Although originally designed for use in sulfuric acid related industries, Alloy 20 Plate is now a popular choice for a wide variety of industries including the chemical, food, pharmaceutical, and plastics industries. In addition, 2.4660 Plate is used in heat exchangers, mixing tanks, metal cleaning and pickling equipment, and piping. Carpenter 20 plate combines excellent corrosion resistance with elevated mechanical properties and relatively easy fabrication.
