AMS 5663 - INCONEL 718 Bars, Forgings & Rings
AMS 5663 is the spec that covers a precipitation hardened INCONEL 718 (UNS N07718) alloy in bars, forgings, and rings. This nickel-chromium alloy is strengthened with niobium, molybdenum, aluminum, and titanium and provides excellent mechanical, fatigue, and corrosion properties in the presence of both cryogenic and high-temperature environments.
The parts that were originally manufactured to specification AMS 5662 can be subjected to a heat treatment in accordance with specification AMS 5663 to achieve full precipitation hardened properties. The routine sequence of the heat treatment consists of an 8-hour dwell at 1325°F (718°C), furnace cooling at 100°F/hr (55°C/hr) to 1150°F (621°C), holding 8 hours, and then air cooling.
Product Forms & Size Range Of AMS 5663
Fighter Jet Metals supplies INCONEL 718 in multiple product forms with diameters ranging, ensuring compatibility with complex engineering and machining requirements.
NICKEL 718 Round Bar diameters range from 0.125″ to 14.00″ diameter.
