Inconel alloy is a high-strength superalloy resistant to corrosion, high pressure and extreme temperatures. These characteristics make Inconel an ideal choice for use in extreme environments such as aerospace and marine with its resistance to salt.

A superalloy is used for situations where high-performance and temperature equipment is necessary. Where other alloys would melt, super alloy would be able to continue. The likes of rocket and jet engines need superalloy. Power plants and other areas of the oil and gas industry apply superalloy.

Aerospace, automotive, chemical processing, electrical, marine, mining, oil & gas, and petrochemical industries all need superalloys.

Cobalt is used in superalloys due to its good magnetic properties, high-temperature strength, and the ability to resist both corrosion and wear-and-tear. The crystallographic nature of cobalt allows these kinds of traits to be present.

There are three different classes of superalloys: nickel, iron, and cobalt-based alloys.

The strongest superalloy is called Inconel. It is one of the strongest metals in the world and can continue to work through some of the hottest possible temperatures – as well as other extreme conditions. It is made up of austenite, nickel, and chromium.

Superalloys will be able to resist corrosion and oxidation when operating at extremely high temperatures in jet engines, for example. Their biggest trait is the ability to continue working during some of the most extreme conditions.

Nickel-based superalloys possess fatigue strength, thermal stability, and resistance to corrosion. Under severe conditions, nickel can survive and continue performing. In fact, nearly 50% of aircraft engines are made up of nickel-based superalloys.

There are four ways to increase a metal’s strength and durability. Cold working, solid-solution hardening, precipitation hardening, and transformation hardening.

The strengthening mechanisms of superalloys are as follows: strengthening grain refinement, strain hardening, solid solution strengthening, and precipitation or age hardening.

Superalloys have high strength, high thermal resistance, machinability, shape memory, corrosion resistance, and a low coefficient of thermal expansion.
