Product Description and Application
Inconel 718 is a Fe-Ni-Cr based precipitation-hardening deformable high-temperature alloy. Its long-term operating temperature range is -253~650℃, and its short-term operating temperature is 800℃. Below 650℃, it exhibits high strength, good toughness, and oxidation and corrosion resistance in both high and low-temperature environments. It also possesses good processing and welding properties and long-term organizational stability.
Used to manufacture rings, blades, fasteners, and structural components in aerospace and petrochemical applications. It is used to manufacture various parts in the petrochemical industry, with good mass production capabilities and performance. During vacuum consumable remelting, a helium cooling process can be used to effectively reduce niobium segregation. Using injection molding to produce rings can reduce costs and cycle times, while superplastic forming can expand the production range. Suitable for manufacturing rings, blades, fasteners, and structural components in aerospace and petrochemical applications.
