Dear friends,
Which flange group in ASME B16.5 can cover the B564-N06022(Hastelloy-C22) flange?
There is no B564-N06022 material in Table 1A of ASME B16.5.

RE: Hastolloy-C22 flange
In my ASME B16.5-2003, the material you are looking for is listed with Material Group 3.8 of Table 1A on page 5, but is apparantly covered by ASTM B462 instead of ASTM B564. Review those ASTM standards for their scope of materials.
