Incoloy alloy 925 is a precipitation-hardenable nickel-iron-chromium alloy that contains additions of molybdenum, copper, titanium, and aluminum. The alloy has excellent mechanical properties at both ambient and elevated temperatures, making it suitable for use in a wide range of applications, including sour gas and oil production, aerospace, chemical processing, and marine engineering.
Incoloy alloy 925 is known for its high strength, which is achieved through a combination of solid solution strengthening and precipitation hardening. It also exhibits excellent resistance to corrosion and oxidation in a variety of environments, including those containing sulfides and chlorides.
The addition of molybdenum and copper to the alloy improves its resistance to pitting and crevice corrosion, while the titanium and aluminum additions enhance its resistance to intergranular attack. The combination of these elements makes Incoloy alloy 925 highly resistant to stress corrosion cracking and hydrogen embrittlement.
The alloy is typically supplied in the solution annealed condition, and can be easily fabricated using common techniques such as welding, brazing, and machining. After fabrication, the alloy can be precipitation hardened to achieve its maximum strength.
Incoloy alloy 925 is available in a range of forms, including round bars, flat bars, forgings, and wire. It is also available in various sizes and dimensions to meet the specific needs of different applications.
Overall, Incoloy alloy 925 is a versatile and high-performance alloy that offers excellent strength, corrosion resistance, and durability in demanding applications.
