flange pressure ratings for A182 F316LN

flange pressure ratings for A182 F316LN

(OP)
I need to find working pressure data for a flange material.  It is A182F316LN.  B16.5 does not list this material.  I see the material in other ASME publications so I believe it to be a legitimate material.  Any help would be appreciated.
thanks
Mark

RE: flange pressure ratings for A182 F316LN

Comparing in ASTM A 182 the nickel range is more narrow (11-14%) than permitted for 316L (10-15%)and nitrogen content is higher, up to 0.10% for 316L and between 0.10% and 0.16%.  I don't know what the nitrogen content might affect.

pipe15,
Refer ASME II-D, for the material ASME SA182-316LN (S31653), listed as acceptable material for use as forged flange in nuclear pressure vessel design (ASME III), up to some 430 deg C.
