Nimonic alloy 263 is an age-hardenable nickel-cobalt-chrome-molybdenum alloy which was designed to have excellent fabrication characteristics in the annealed condition but also very good aged strength properties. Alloy 263 is easier to form or weld than other materials such as Waspaloy or Rene 41 and exhibits excellent intermediate temperature ductility. Alloy 263 is supplied in the annealed condition and its excellent ductility in this condition makes it suitable for cold forming as well as hot working. Alloy 263 can be welded using matching composition filler wire in both TIG and MIG forms. The recommended heat treatments for Nimonic 263 are as follows:
Extruded Bar:
Solution Treatment – 1150 °C for 1.5-2.5 hours + water quench
Ageing Treatment – 800 °C for 8 hours + air cool
(As per BS HR10 / AMS 5886)
Hot-rolled Sheet
Solution Treatment – 1150 °C for 0.5 hours + water quench or air cool
Ageing Treatment – 800 °C for 8 hours + air cool
(As per BS HR206/ AMS 5872)
Cold-rolled Sheet
Solution Treatment – 1150 °C for 3-10 mins + water quench or fluidized bed quenching
Ageing Treatment – 800 °C for 8 hours + air cool
(As per BS HR206 / AMS 5872)
