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
