Alloy A286/660
Is an austenitic precipitation-hardenable stainless steel that is generally configured for long-term and high-temperature use, with a service temperature reaching up to 700 °C.
It is considered as an iron-based superalloy due to its high strength and resistance to corrosion at high temperatures.
Used in aviation and power engineering for heavy-duty rotors, gas turbine blades, steam turbines, pressure equipment parts and reactors, jet engines and rockets, exhaust systems. Also used in cryogenics.
