Introduction to high temperature alloys
Corrosion-resistant superalloys are widely used in extreme environments where extremely high heat and corrosion resistance are critical to the integrity of the finished product. These high-temperature alloys are widely used in chemical and petrochemical processing, power plants, and the oil and gas industry.
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 (cobalt). ).
Superalloys, also known as high-performance alloys, have become the steels of choice for corrosion resistance and versatility.

Little knowledge about high temperature alloys
The term "superalloy" was first used shortly after World War II to describe a group of alloys developed for turbochargers and aircraft turbine engines where high performance was required at high temperatures.
