Inconel 718 is a precipitation-hardened deformation superalloy based on iron, nickel, and chromium, engineered for high-performance applications across extreme environments. With a long-term operating temperature range from -253°C to 650°C, and short-term capabilities reaching up to 800°C, this alloy offers an excellent balance of mechanical strength, toughness, and resistance to oxidation and corrosion.
Its superior structural stability, good machinability, and weldability make Inconel 718 ideal for manufacturing high-strength aerospace and petrochemical components, including turbine rings, blades, structural fasteners, and high-temperature hardware. Inconel 718 performs reliably in both cryogenic and high-heat environments, making it especially well-suited for high-demand applications.
The alloy supports vacuum consumable remelting with helium gas cooling, which helps reduce niobium segregation, improving material uniformity. It can also be jet-formed into rings, helping manufacturers cut costs and shorten production cycles, while superplastic forming further expands its application range for complex, high-performance components.
Widely used in aerospace, aviation, and petrochemical industries, Inconel 718 has demonstrated excellent batch production performance and in-service reliability, and remains a material of choice for demanding structural parts that require long-term durability and heat resistance.
