HIP/heat treatment for conventional liquid bipropellant rocket engine

Looking for HIP/heat treatment on two 3D-printed Inconel 718 parts for a conventional liquid bipropellant rocket engine. Unfortunately, I cannot share part files until we have come to a conclusion on an NDA. However, I can share that we have two parts, both with large portions of internal negative volume.
Part One:
Max dimensions: 27cm x 27cm x 33.5cm
Mass: 13.94 kgLabel: de Laval nozzle

Part Two:
Max dimensions: 27cm x 27cm x 9cm
Mass: 12.89 kg
Label: Injector
HIP:2125 deg F for 4 hours at 14.75 ksi
Heat Treat:Solution anneal at 1800°F for 1 hour followed by quench, plus precipitation hardening at 1325°F for 8 hours, furnace cool 20°F/hr to 1150°F, followed by air cooling.
We would hopefully have the HIP and heat treat done by the middle of next week. I understand that this is very short notice -- and may rise prices due to the rush -- but I appreciate all that can be done. The previous company we were working with began taking too long to respond and we need to move on with out them.
