Alloy 625

NeoNickel > Alloys > Alloy 625

A nickel-chromium-molybdenum-niobium grade, Alloy 625, commonly referred to as Inconel 625, offers outstanding corrosion resistance and superb weldability.

The addition of niobium provides high strength without the need for heat treatment. NeoNickel also offers Alloy 625 sheet with a combination of low-cycle fatigue and deep drawing quality.

Perfect for applications in the Aerospace industry

Alloy 625 can be used in a variety of applications including:

  • Aircraft ducting and exhaust systems
  • Engine thrust-reverser systems
  • Turbine shroud rings
  • Bellows, expansion joints
  • Gaskets and damper seals
  • Motorsport exhaust and clamps
  • Weld overlay and spacers for heat recovery systems
  • Furnace muffles
  • Valve seats and components

About Alloy 625

Alloy 625, commonly referred to as Inconel 625, demonstrates an excellent combination of corrosion resistance and high strength. Due to the high nickel content, Inconel Alloy 625 is immune to chloride-induced stress corrosion cracking. It also has good resistance to pitting and crevice corrosion.

NeoNickel offers Alloy 625 sheet certified to both UNS N06625, 625 LCF® and ATI 625 HP® (UNS N06626). The 625 sheet meets the low-cycle fatigue properties specified in UNS N06626 and is also produced and certified as DDQ (deep drawing quality).

Resulting from the alloy’s excellent thermal stability, Alloy 625/Inconel 625 is the alloy of choice for weld overlay applications in the oil and gas/petrochemical and refineries markets.
