A286/grade 660

  1. Brief introduction:

    It is a Fe-25Ni-15Cr based superalloy with comprehensive strengthening of molybdenum, titanium, aluminum, vanadium and trace boron. It has high yield strength and long-lasting, creep strength below 650 ° C, and has good processing plasticity and satisfactory welding performance. Suitable for the manufacture of high-temperature bearing components for aerospace engines operating at temperatures below 650℃, such as turbine disks, press plates, rotor blades and fasteners. The alloy can produce deformed products of various shapes, such as discs, forgings, plates, rods, wires and rings.
