AMS 5962 is a designation of Nickel Inconel 718, itself a nickel-chromium alloy with high strength, corrosion and oxidation resistance, and excellent tensile and impact strength at cryogenic temperatures.
Full chemical composition is 52.5Ni – 19Cr – 3.0Mo – 5.1Cb (Nb) – 0.90Ti – 0.50Al – 18Fe.
This designation is made by solution annealing at 1775°F (968°C) followed by rapid cooling, usually in water, and precipitation hardening at 1325°F (718°C) for 8 hours and furnace cool to 1150°F (620°C).
It is available as bar and wire that’s up to 38mm (1½ inches) in diameter. It is best suited for corrosion and heat-resistant work.
AMS 5962 is an excellent choice for parts where there is a concern of rupture life, notch rupture life, and rupture ductility.
