ASTM B462 PDF

Nickel Alloy 20 Forged Fittings. Because of good resistance to corrosion, crevice corrosion, and pitting, this stainless steel alloy is widely used for manufacturing tanks, heat exchangers, process piping and pickling equipment. Alloy 20 forged fittings are used in various applications throughout the chemical process industry, pharmaceuticals, synthetic rubber, plastics, industrial heating equipment, pulp and paper manufacturing. A sufficient discard shall be made from each ingot to secure freedom from injurious piping and undue segregation.
