Alloy 20 is a austenitic nickel-iron-chromium alloy developed for maximum resistance against acid attack, specially sulfuric acid. It offers excellent resistance to pitting, crevice corrosion and general corrosion in chemicals containing chlorides and sulfuric, nitric, phosphoric and acids. For stabilization against sensitization and resultant intergranular corrosion Alloy 20 contains niobium. With relatively easy fabrication and elevated mechanical properties Alloy 20 also provides excellent corrosion resistance.
