Cast spool with flanges - Unlisted material A494 CW6MC -N26625

[Clareok]

Hi - have short spools 6 & 8" to be casted from A494 CW6MC with both ends formed into 600# rated flanges. This material is not listed in B31.3, II D, B16.5, B16.34
From ASTM A494 i can get the tensile & yield values but struggling to elevated temperature allowables & P/T ratings.
What options do i have in this situation?

It's a nickel base steel, ALLOY 625, Cast N26625. I would ask the vendor making the spool for MTR's.
