Hot forming 625 Inconel elliptical heads

[CoFe2]

Wondering if anyone has some knowledge on additional requirements for hot forming elliptical heads made from SB-443 N06625 Inconel, as far as post forming annealing or heat treat when building to ASME Section VIII. I have looked around material specs and Section VIII but only find requirements for Carbon steels and ferritic steels but nothing on high nickel alloys.

Thanks!

Chrisbnwc, if this is Div 1 work, see UNF-79

The problem with sloppy work is that the supply FAR EXCEEDS the demand
