An Introduction to Inconel 718:

Inconel 718 castings are typically used for jet engine castings, high-speed airframe castings, land-based gas turbine castings, oil field castings, rocket motor castings, spacecraft, nuclear reactor component castings, pumps and castings for cryogenic applications. Inconel 718 is a precipitation-hardenable nickel-chromium alloy containing relatively high amounts of iron, niobium, and molybdenum along with smaller quantities of aluminum and titanium. Inconel 718 castings provide excellent corrosion resistance and high strength. Inconel 718 castings can be easily welded and are resistant to postweld cracking. The alloy has excellent creep-rupture strength at temperatures up to 1300°F (700°C). Inconel 718 is also known as UNS 07718, UNS N07718, Udimet 718, Allvac 718, Pyromet Alloy 718 and Haynes Alloy No. 718.

Why Vacuum Precision Cast Inconel 718?

Hardness, toughness and high temperature strength make nickel-based superalloys extremely difficult to machine. Vacuum precision casting avoids this problem by producing accurate parts that are near-net shape. While the processes used for making wax patterns and ceramic cores are complicated, vacuum precision casting need little final machining. This makes vacuum precision casting cost-effective for more complex parts required in higher volumes.

In the early days of super alloys, parts were forged rather than cast. However, the development of vacuum precision casting eliminated the porosity problems that plagued early attempts at casting. Today almost all investment casting of super alloys is performed under vacuum.
