High Strength Alloy 718 is a precipitation hardenable nickel-based alloy designed to display exceptionally high yield, tensile and creep-rupture properties at temperatures up to 1300°F (704°C). The age-hardening response of Alloy 718 permits annealing and welding without spontaneous hardening during heating and cooling. Alloy 718 has excellent weldability when compared to the nickel-base super alloys hardened by aluminum and titanium. Nickel-based Alloy 718 is used in aircraft engine parts and high-speed airframe parts such as wheels, buckets, spacers, and high temperature bolts and fasteners.

Inconel Alloy 718 is a nickel super alloy frequently used for cryogenic storage tanks, turbines, down hole shafting and well head parts. High tolerance to extremely high and low temperatures allow cryogenic storage tanks steel material Inconel 718 to be welded and annealed into products that will withstand extreme conditions. Other uses include jet rocket, nuclear fuel, and pump body components.

Gas turbine components steel material Alloy 718 is a precipitation-hardenable nickel-chromium alloy containing large amount of iron, niobium and molybdenum. It also contains small amounts of titanium and aluminum. It is known for its corrosion resistance, high strength and outstanding weldability.

Uses for structure steel Inconel 718 alloy tend to be in the field of gas turbine components and cryogenic storage tanks. Jet engines, pump bodies and parts, rocket motors and thrust reversers, nuclear fuel element spacers, hot extrusion tooling. Nickel-based alloy Inconel 718 is also commonly used in High temperature bolts, nuts and fasteners, Airframe parts, Gas turbine engines, Cryogenic tanks and Nuclear engineering applications.
