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.

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.
