Stainless steels and austenitic nickel based super alloys are commonly used in the metal processing industry. Typically, these materials are a mixture of high strength and corrosion resistance. These alloys are also often highly alloyed. These alloys are used in a variety of industries, including the chemical, transport, and energy industries.
The use of these alloys in the energy industry has increased with the depletion of fossil fuels. They have been widely used in thermal power plants. These alloys also offer good corrosion and oxidation resistance at high temperatures. These alloys are also useful in applications requiring resistance to fatigue.
Ni-based superalloys are primarily produced by vacuum induction melting. The cleanliness of the alloy is a key factor in the process. Typically, the process involves the purification of the alloy to remove contaminates such as bismuth, lead, and tin.
The single crystal nature of these alloys provides them with high strength, ductility, and corrosion resistance. This makes them ideal for demanding industries, such as those in the aerospace and defense sectors. These alloys are also used in land base gas turbines. The growing number of these engines will likely drive the global single crystal nickel based superalloys market.
Ni-based superalloys were developed to improve the efficiency of thermal power generation. Today, these materials are widely employed in aircraft engines, high-performance racing car engines, and turbine engines. They are also used in downhole equipment, pump wheels, and several components of extrusion machines.
