Dear Experts,

one of our client is asking for Solution annealing for complete vessel
vessel size - 1300 ID x 6500 mm long, thickness 8 mm with lots of nozzles.
whether it is possible.
at higher temperature of 1100 Deg C and rapid cooling in water, vessel will distort completely.

It looks material is INCONEL 617 or similar. We did the same heat treatments, heating rate 150C/hr holding temp 1100C holding time 1 hr and uncontrolled cooling in air not in water.

U have to do like sprinkle type flow on the vessel. Do not immerse or forced water flow on the because it will get collapsed. Be cautious in designing your type of water flow. It is very important.

What is the purpose of solutions annealing for Inconel 617. Generally it is being used for high temperature service

That is correct The inconel 617 material were used in gas turbine After 33000 hours operation both pieces inner casing and combustion chambers needs to stress relieves. That is why heat treating periodically
