Alloy SteelSheet/Plate
Description (English)
Inconel 617 is a solid-solution strengthened nickel-chromium-cobalt-molybdenum alloy offering exceptional high-temperature strength, outstanding oxidation and carburization resistance up to 1100°C, and excellent weldability. It is widely used in gas turbine combustion chambers, nuclear reactor heat exchangers, petrochemical reformer tubes, and furnace components. Supplied as solution annealed plate per ASTM B168 / AMS 5887.
