Incoloy A-286 nickel-based alloy overview:
Incoloy A-286 nickel-based alloy is Fe-25Ni-15Cr-based high temperature alloy, which is comprehensively strengthened by adding molybdenum, titanium, aluminum, vanadium and trace boron. Below 650 ℃, it has high yield strength, long-lasting, creep strength, and has good processing plasticity and satisfactory welding performance. It is suitable for manufacturing high-temperature bearing parts of aero-engines, such as turbine discs, press discs, rotor blades, and fasteners, which work under 650 ℃ for a long time.
The alloy can produce deformed products in various shapes, such as disks, forgings, plates, rods, wires and rings. Incoloy A-286 nickel-based alloy improves the purity of the alloy, limits the gas content, controls the content of low melting point elements, and adjusts the heat treatment system, so that the alloy's thermal strength and long-term use performance are improved.
