Alloy 625

About Alloy 625

Alloy 625, also known as Inconel 625, is a nickel-chromium-molybdenum alloy with niobium added. This provides high strength without a strengthening heat treatment. Alloy 625 resists a wide range of severely corrosive environments and is especially resistant to pitting and crevice corrosion.

Alloy 625 is typically used in:

  • Chemical processing
  • Sour gas wells
  • Aerospace and Marine engineering
  • Pollution-control equipment
  • Nuclear reactors
