AISI 926 Characteristics

  • Guaranteed PREN ≥ 43 for extreme resistance to localized chloride pitting and crevice attack.
  • High nitrogen content increases mechanical yield strength significantly over standard austenitics.
  • Outstanding resistance to stress corrosion cracking in concentrated saline and acidic environments.
  • Superior resistance to phosphoric acid containing fluoride and chloride impurities.
  • Fully austenitic structure with exceptional impact toughness down to cryogenic temperatures.

Applications

  • Offshore oil & gas subsea manifolds, platforms, and process piping bolting.
  • Flue-gas desulfurization (FGD) scrubbers, absorber towers, and dampers.
  • Seawater reverse-osmosis desalination high-pressure pumps and piping.
  • Phosphoric acid fertilizer production evaporators and agitators.
  • Marine exhaust gas cleaning systems (EGCS) and scrubber fasteners.
