pressure section of the compressor and discs as well as some blades of the turbine section. The precipitation of this nickel – (aluminum, titanium, and niobium) phases in Inconel 718 Flat Bars is induced by heat treating in the temperature range of 1100 Degree F to 1500 Degree F.

This is the preferred treatment in tensile – limited applications for Inconel 718 Threaded Bars as it produces the best transverse ductility in heavy sections, impact strength and low temperature notch tensile strength. Common Applications of Inconel 718 Hollow Bars: Jet engine components, Oil & gas, and Gas turbine operations. Inconel 718 Hexagonal Bars has good mechanical properties – tensile, fatigue and creep – rupture.

Inconel 718 Triangular Bars is often used in aerospace, rocket motors, space shuttles, spacecraft, nuclear reactors, turbo pump seals, tooling and pumps. Inconel 718 Bars has excellent weldability when compared to the nickel – base super alloys hardened by aluminum and titanium. The results indicated that the fine – grained ring forgings can be obtained by forging the fine – grained Inconel 718 Rods.
