A286 belongs to the American brand Naming convention, which is equivalent to domestic superalloy GH2132. It belongs to Fe-25Ni-15Cr based high-temperature alloy and can maintain high strength and good corrosion resistance at a high temperature of 704 ℃.
It has good processing plasticity and satisfactory welding performance. Suitable for manufacturing high-temperature load-bearing components of aircraft engines that operate for a long time below 650 ℃, such as turbine discs, press discs, rotor blades, and fasteners. This alloy can produce various shapes of deformed products, such as discs, forgings, plates, rods, wires, and annular parts.
High quality A-286 alloy is developed on the basis of A-286 alloy. As long as it improves the purity of the alloy, limits gas content, controls the content of low melting point elements, and adjusts the heat treatment system, the thermal strength and long-term performance of the alloy can be improved.
A286 Similar grades Incoloy A-286, UNSS66286 (USA), ZbNCT25 (France), P.Q.A286 (USA).
