KX Alloy263 Uns Light Rod Plate Structural Operating Temperature Range For High Temperature Alloy
Product Description and Application
Alloy263 is also known as NO7263, Nimonic263, GH4163
Alloy263 superalloy is Ni-Cr-Co base precipitation hardened deformed superalloy, the use temperature can reach 850℃. The alloy has good oxidation resistance under 800℃, high yield strength, high creep strength, small strain aging crack tendency, good cold and heat fatigue resistance. The alloy has satisfactory formability and weldability. It is suitable for making plate welded structural parts and bearing parts of main combustion chamber and afterburner on the aircraft engine.
