Alloy 020 (UNS N08020, W. Nr 2.4660) is a nickel-iron-chromium alloy which has the addition of copper and molybdenum. With the additions of niobium Alloy 020 is stabilized against sensitization and resultant intergranular corrosion. Alloy 020 has excellent resistance to general corrosion, pitting and crevice corrosion and is commonly used for chemical, pharmaceutical and food processing, tanks, piping, heat exchangers, pumps, Kevlar production and much more.
