A superalloy is a “high-performance” alloy with outstanding qualities, making it valuable for use in power industries as well as in the aerospace industry. These qualities include a high level of mechanical strength as well as a high resistance to creeping at high temperatures. These high-performance alloys also have excellent surface stability and are resistant to corrosion and oxidation. Superalloys usually have a cubic crystal structure that is austenitic and face-centered and a base alloying element of nickel or cobalt, or nickel-iron.
The term “superalloy” was coined after World War II, when these alloys were used in the development of supercharged aircraft engines. Today, there’s no question that superalloys are a top choice for use in products that must have a high level of resistance to corrosion. The versatility of these superalloys is also another key aspect in their wide use in industry.
The high corrosion resistance of superalloys makes them ideal for use in extreme environments. In these environments, high resistance to heat and corrosion are the key to a metal product’s quality, which is why the integrity of these superalloys is so important. Superalloys are widely used in the oil and gas industry, in the development of power plants, and in petrochemical and chemical processing.
Nickel-based industrial superalloys contain other elements within the alloys. These elements can include chromium (Cr), titanium (Ti), aluminum (Al), molybdenum (Mo), tungsten (W), niobium (Nb), tantalum (Ta), and also cobalt (Co).
The list of nickel-based superalloys used in industry include Alloy C-276, Alloy X, Alloy 718, and Alloy 20. Superalloys are used in a wide range of industrial applications, including the production of rocket engines and turbine blades in the aerospace industry. They are also used to create submarines, nuclear reactors, and tubing for heat exchangers.
Without a doubt, the development of superalloys has been a gamechanger for industry, as the surface stability, strength, and corrosion and oxidation resistance of these alloys make them incredibly valuable for a variety of uses.
