Nimonic 263 alloy is a nickel-chromium-cobalt-based precipitation hardening deformed superalloy. Its long-term service temperature is below 800 degrees Celsius, and the short-term service temperature can reach 8500 degrees Celsius. The alloy has high oxidation resistance, high yield strength and creep strength, less strain-aging crack tendency, and good resistance to cold and hot fatigue. The alloy has satisfactory formability and weldability. 
Nimonic263 heat treatment system.
The standard heat treatment regime for each variety is:
Solution treatment: 1150 10;Aging treatment: 800 10 8h ac. These include:
Forgings and rings, solution holding time (1.)5-2.5) h, water-cooled;
tube, solution holding time 15 min, air cooling or appropriate cooling;
Strip, solution holding time: δ 4mm, (5-l5)min, air cooling;4mm10mm, 120min, air cooled;
and hot-rolled forged bars, solution holding time: d 8mm, 30min, water cooling (air cooling or oil cooling);d > 8 mm, (90-150) min, water-cooled (air-cooled or oil-cooled).
