Inconel 617 alloy exhibits excellent corrosion resistance in thermal corrosion environments such as sulfidizing conditions, particularly in cyclic oxidation and carburization environments up to 1100°C. These corrosion resistance properties, coupled with outstanding mechanical properties, make this alloy especially suitable for high-temperature applications.
Inconel 617 is a nickel-chromium-cobalt-molybdenum alloy with excellent mechanical properties at high temperatures and resistance to high-temperature corrosion phenomena, such as oxidation and carburization.
Characteristics of Inconel 617 include:
- Excellent transient and long-term mechanical properties at temperatures up to 1100°C.
- High resistance to oxidation at 1100°C.
- High resistance to carburization at 1100°C.
- Good weldability.
