Inconel 718

DEFINITION OF Inconel 718 : Inconel 718 is a high-strength, high-temperature and corrosion resistant nickel-chromium alloy.

Since the mid-1980s, Dynamic Flowform has used the precision flowforming process to produce hundreds of different components out of materials such as inconel 718 to net or near-net shape. Flowforming is a cold forming process for the production of seamless, dimensionally precise tubular components. Beside offering lower cost alternatives to machining from solid bar, due to the cold working of the material, the microstructure of flowformed inconel 718 is superior to that of bar or sheet. Flowformed inconel 718 is used in military, nuclear and industrial applications.

The flowforming process offers the designer an opportunity to explore the very high tensile strength, with excellent ductility. The grain refinement and grain directionality imparted by the flowforming process is very advantageous, too. The extremely fine grain structure (ASTM 10-12) is what one would expected from solution heat treating a heavily cold-worked (70% wall reduction) structure at 1750 F post-flowform heat treatment.

Customers can take advantage of the flowforming characteristics by incorporating them into their designs. In addition to the benefits listed above, flowforming produces inconel 718 components with seamless constructions. Quite often, Dynamic Flowform is able to integrate more than one previously separate component into the same inconel 718 structure.

Our flowformed components range in size from diameters of 0.866" to 25.600" (22-650mm), wall thicknesses from 0.006" to 0.600" (0.15-15mm) with lengths up to 26.5 ft. (8 meters). Since flowform poses no limitations on the relationship between components diameter and wall thickness, quite often we produce large diameters with precise thin walls.
