INCONEL617 alloy properties and uses:
Inconel617 is a solid solution, strengthened nickel-chromium-cobalt-molybdenum alloy with excellent comprehensive high temperature strength and oxidation resistance, which perfectly combines metallurgical stability, strengthening and high temperature and oxidation resistance. Increases its antioxidant properties.
INCONEL617 alloy has corrosion resistance in many corrosive liquid environments.
INCONEL 617 alloy has excellent corrosion resistance in hot corrosion areas such as sulfurized environments, especially in oxidizing and carbonizing environments up to 1100°C cycles. These corrosion resistances, combined with excellent mechanical properties, make this alloy particularly suitable for use in In the high temperature field, it has good instantaneous and long-term mechanical properties at high temperatures up to 1100°C.

Inconel617 heat treatment method
In order to obtain suitable properties, the solution treatment temperature is 1150ºC-1200ºC, and it must be water quenched to obtain creep resistance, and those with a thickness of less than 1.5mm can also be rapidly air-cooled.
The stress relief annealing temperature is up to 870°C.
During all heat treatments, the previously mentioned precautions for keeping clean should be taken into account.
