Incoloy Alloy 020 Introduction to Characteristics and Execution Standards

Common Trade Names: Incoloy Alloy 020, Alloy 20, Carpenter 20, 20CB-3.

INCOLOY alloy 020 (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, pharmaceuticals, and food and synthetic materials. INCOLOY alloy 020 is readily fabricated to produce mixing tanks, heat exchangers, process piping, pickling equipment, pumps, valves, fasteners and fittings. 

Available Product Forms: Pipe, tube, sheet, strip, plate, round bar, flat bar, forging stock, hexagon and wire.

Specifications:INCOLOY alloy 020 is designated as UNS N08020.
