Inconel 617 (UNSN06617 / W.Nr.2.4663) is a solid solution, strengthened nickel-chromium-cobalt-molybdenum alloy with excellent comprehensive high temperature strength and oxidation resistance.
The alloy also has corrosion resistance in a wide corrosive environment, and is easy to form and weld with existing technology.
The high nickel and chromium content makes the alloy resistant to corrosion in various reducing and oxidizing environments.
The combined effect of aluminum and chromium provides the alloy's high temperature oxidation resistance. Cobalt and molybdenum give the alloy solid solution strengthening ability
