S66286

Product:S66286 is A Fe - ni - cr 15 25 based high temperature alloy, molybdenum, titanium, aluminum, vanadium and trace boron composite reinforcement. Under 650 degree has high yield strength and lasting and creep strength, and has good processing plastic and satisfactory welding performance. Suitable for manufacturing in the long-term work of aircraft engine under 650 degree high temperature bearing parts, such as turbine disc, press plate, the rotor blades and fasteners, etc. Can produce all kinds of deformation in the shape of the alloy products, such as plate, forgings, plate, bar, wire and circular pieces, etc.
