Alloy 925

Introduction :

Alloy 925 is a precipitation-hardenable nickel-iron-chromium alloy with added copper and molybdenum. It exhibits high strength and excellent resistance to pitting, crevice corrosion, and stress-corrosion cracking in many aqueous environments containing chlorides and sulfides.

Many different industries rely on Alloy 925 for a number of uses including:

  • Valves, hangers, packers, and tubulars for sour gas production
  • Marine fasteners and pump shafts

Often sold as Inconel® 925, alloy 925, it is known for a number of different unique properties including:

  • Protection in rusting and reducing atmosphere
  • Resistance to chloride ion stress-corrosion furious
  • Outstanding resistance to pitting and crevice corrosion
