Superalloys or high-performance alloys are alloys that exhibit excellent mechanical strength and creep resistance, good surface stability, and corrosion and oxidation resistance at high temperatures. They usually have an austenitic face-centered cubic crystal structure containing nickel, cobalt or nickel-iron alloy elements. The development of superalloys is mainly promoted by the aerospace and power industries.

Corrosion-resistant superalloys are widely used in extreme environments. In these environments, extremely high heat resistance and corrosion resistance are critical to the integrity of the final product. These superalloys are widely used in chemical and petrochemical processing, power plants, and the oil and gas industries.

Many industrial nickel-based superalloys contain alloying elements, including chromium (Cr), aluminum (Al), titanium (Ti), molybdenum (Mo), tungsten (W), niobium (Nb), tantalum (Ta) and cobalt (combined ).

Super alloys, also known as high-performance alloys, have become the steel of choice for corrosion resistance and versatility.

Small knowledge of superalloy

The term "superalloys" was first used shortly after World War II to describe a group of alloys developed for turbochargers and aircraft turbine engines that require high performance at high temperatures.
