ASTM A269 UNS S31254 Allowable Stress

[MikeRis]

Hi,
I am looking for the allowable stress values for ASTM A269 UNS S31254 material for a wall thickness calculation to ASME B31.3 but cannot locate the material grade in ASME B31.3 or ASME Section II Part D.

Does anyone know where I can find this info?
Thanks.
Mike

Is A269 even allowed? (There is no SA269)
The alloy is listed, but it may be under different specifications.
Is this pipe or tube?
Welded or seamless?
You need to find the correct specification.

It is seamless tubing.

Try SA213 or SA312.
And good luck finding this alloy in seamless.
Could you use one of the other 6%Mo alloys?
