Alloy 20/N08020

Category：Anti-corrosion alloy» | Date：2023-03-17

  1. Brief introduction:

    Alloy 20 is a Ni-Fe-Cr alloy with additions of Cu and Mo, and it also contains Nb for stabilization against sensitization and resultant intergranular corrosion.

    Alloy 20 has excellent resistance to general corrosion, pitting and crevice corrosion in chemicals containing chlorides and sulfuric,phosphoric and nitric acids.

    Alloy 20 is used for heat exchangers, tanks, piping, pumps, valves and other process equipment.
