Haynes 617 is a nickel-chromium-cobalt-molybdenum alloy with excellent high-temperature strength, good oxidation resistance, and excellent resistance to carburization and sulfidation. It is commonly used in gas turbine engine components, industrial furnace applications, and other high-temperature applications.
Haynes 617 has a nominal composition of 44.5% nickel, 20-24% chromium, 8-10% molybdenum, 0.5% maximum copper, 0.15% maximum carbon, 1.0% maximum cobalt, 0.5% maximum silicon, 1.0% maximum manganese, 0.015% maximum sulfur, 0.015% maximum phosphorus, and the balance iron.
Haynes 617 offers excellent mechanical properties at high temperatures, making it ideal for use in gas turbine engine components such as combustion liners, transition ducts, and exhaust systems. Its high-temperature strength and resistance to carburization and sulfidation make it suitable for use in industrial furnace applications such as radiant tubes, muffles, and retorts.
In addition to its high-temperature strength and resistance to oxidation and carburization, Haynes 617 also offers good resistance to thermal shock and thermal fatigue. This makes it ideal for use in applications that require resistance to cyclic heating and cooling, such as gas turbine engine components and industrial furnace applications.
Overall, Haynes 617 is a versatile high-temperature alloy that offers excellent mechanical properties and resistance to corrosion and oxidation in high-temperature environments. Its use in gas turbine engine components and industrial furnace applications has been well-established, and it continues to be an important material in these industries.
