(OP)
This is my first thread. Hi to everybody.
My question:
I need a flange made in uns n08904 but I can't find it in asme sa-182.
What is the right specification for uns N80904 forgings?

Thank you.

I use:
SA-240 for plates
SB-366 for fittings
SB-673 for welded pipe
SB-677 for seamless vpipe & tubes

RE: uns n80904 & forgins

The UNS N08904 is 904L. You could machine the flange from plate; see below

ASTM B-625 or ASME SB-625

RE: uns n80904 & forgins

Also forgot, the obvious;

ASTM B-649 Gr 08904, which is a forging specification. This is cited from ASME B16.5-2003 "Pipe Flanges and Welded Fittings", Table 1-A

thank you.
I can't machine the flange from plate (client spec.)
I'll use SB-625 as you write.

I found the S80904 material for plates in SA-240 and in SB-625.
Which one shall I use?
