690-80A

Inconel 690 (UNS N06690)

Nimonic 80A (UNS N07080)

Summary

Inconel 690 is a high-chromium nickel alloy having excellent resistance to many corrosive aqueous media and high-temperature atmospheres. The alloy's high chromium content gives it excellent resistance to aqueous corrosion by oxidizing acids (especially nitric acid) and salts, and to sulfidation at high-temperatures. In addition to its corrosion
resistance, alloy 690 has high strength, good metallurgical stability, and favorable fabrication characteristics.

A nickel-chromium alloy made precipitation hardenable by additions of aluminum and titanium. The alloy has good corrosion and oxidation resistance and high tensile and creep-rupture properties at temperatures to ℃.Used for gasturbine components (blades, rings, and discs), bolts, tube supports in nuclear steam generators, die-casting inserts and cores, and exhaust valves in internal-combustion engines.
