Nickel Alloy 625

A nickel-chromium-molybdenum alloy with the addition of niobium for strengthening. This alloy resists many severely corrosive environments and is very resistant to pitting/crevice corrosion. Alloy 625 has excellent weldability and service temperatures range from cryogenic to 1800 deg F. The alloy resists scaling at high temperatures making it suitable for heat shields and furnace hardware, also used in offshore marine and aerospace industries among others and for structures in contact with seawater and subject to high mechanical stresses.

Typical applications: Superphosphoric acid production equipment, flue gas scrubbers components, sour gas equipment, offshore and marine equipment.
