Features:
UNS N08020
Alloy 20 has excellent resistance in chemicals containing sulfuric acid, and has good resistance to environments containing chlorides, phosphoric acid and nitric acid. It contains niobium for stabilization against sensitization and resultant intergranular corrosion. It also has good mechanical properties and fabricability.
Applications:
Chemical, food, pharmaceutical and plastics industries, heat exchangers, mixing tanks, pickling equipment, synthetic rubber manufacturing equipment, pumps, valves and piping.
