Nickel 625 per AMS 5666
Nickel 625 (UNS N06625) is a corrosion and heat-resistant nickel-chromium-molybdenum-niobium alloy specified by AMS 5666. For high-strength, demanding-service applications, it features niobium combined with molybdenum acting to stiffen the matrix, providing strength without a need for further heat treatment after fabrication.
Typically, AMS 5666 Nickel 625 is double melted-EF-AOD (Electric Furnace + Argon Oxygen Decarburization) or VIM (Vacuum Induction Melting)-and then secondary remelt via VAR (Vacuum Arc Remelt) or ESR (Electroslag Remelt) to ensure a consistent chemical composition and maximum mechanical properties.
This alloy exhibits the following desirable properties: outstanding tensile, creep, rupture, fatigue, and thermal-fatigue strength plus good oxidation resistance. In addition, it welds and brazes satisfactorily, and can be used in: aerospace industry, marine applications, and other diverse forms of industries.
