Understanding The Term Superalloys & Its Applications

The term superalloy is used to refer to high-performance alloys that can endure elevated temperatures without running the risk of deformation or corrosion. Among the basic characteristics exhibited by a superalloy are its exceptional mechanical strength, remarkable surface stability, the capability to resist oxidation and corrosion, and the ability to resist creep deformation. Since a superalloy shows resistance to deformation at elevated temperatures, it is fundamentally non-ductile in nature. A superalloy usually contains high levels of strong alloying agents such as cobalt and nickel. Most of the superalloys find applications in high-temperature environments such as jet engines and gas turbines. Some examples of superalloys include Hastelloy, Rene, Waspaloy, and Incoloy.

Superalloys & Its Applications


Hastelloy refers to a range of 22 varied nickel-molybdenum alloys, all of which exhibit a high degree of corrosion resistance. The primary alloying ingredient found in Hastelloys is nickel. The Hastelloy superalloys retain their properties under conditions of elevated temperature and stress. Hastelloys are used in various industries such as aerospace, oil and gas production, chemical processing, pharmaceutical, etc. Among the different grades of Hastelloys are Hastelloy B2, Hastelloy B3, Hastelloy C4, Hastelloy C2000, Hastelloy C276, etc.

Rene 41 Alloy

Rene 41 Alloy is the name given to an age-hardenable, nickel-chromium superalloy. It retains extreme strength at elevated temperature ranges of 1200-1800°F (649-982°C). It is also extremely resistant to oxidation and corrosion. Due to its high strength, it is widely used in environments that require metals to be resistant towards enhanced temperature and extreme stress. This superalloy is widely used in components of jet engines, missiles, springs, and bolts.


Waspaloy is a precipitation-hardenable, nickel-based superalloy that exhibits high strength properties at temperatures up to 1400-1600°F. This superalloy also shows good resistance to corrosion and oxidation. Such properties make this alloy suitable for use in extreme environments. Waspaloy finds application in components of gas turbine engines which demand enhanced strength and resistance towards corrosion at high temperature range up to 1600°F.


Incoloy refers to a nickel-iron-chromium alloy that is available in varied grades such as Incoloy 800, Incoloy 825, Incoloy 020, etc. The grades of this superalloy retain strength at high-temperature settings and exhibit excellent resistance towards corrosion in aqueous environments. Incoloy has a high content of iron and is easy to produce. This superalloy is used in varied industries such as petrochemical processing, nuclear fuel, chemical processing, production of acids, and power plants.
