IncoloyA-286
IncoloyA-286
A286 belongs to the United States brand naming rules, equivalent to the domestichigh temperature alloyGH2132. It is a Fe-25Ni-15Cr-based high-temperature alloy that can maintain high strength and good corrosion resistance at a high temperature of 704°C.
A 286 is Fe-25Ni-15Cr basehigh temperature alloy, adding molybdenum (Mo), titanium (Ti), aluminum (Al), vanadium (V) and trace boron (B) comprehensive strengthening. It has high yield strength and long-lasting and creep strength below 650 ℃, and has good processing plasticity and satisfactory welding performance. Suitable for manufacturing long-term work below 650 ℃aero enginehigh-temperature load-bearing parts, such as turbine disks, press disks, rotor blades and fasteners. The alloy can produce deformed products of various shapes, such as discs, forgings, plates, rods, wires and rings.
high-quality A 286 alloy is developed on the basis of A- 286 alloy. As long as it is to improve the purity of the alloy, limit the gas content, control the content of low melting point elements, and adjust the heat treatment system, so as to improve the thermal strength and long-term service performance of the alloy.
