ASTM A995 6A DUPLEX, B16.34 Approved?

[SmithDavid]

I have a customer that's specified ASTM A995 6a for valves and designed per ASME B16.34.

I'm trying to confirm if this Cast version of Super Duplex is a recognized material in B16.34.

ASTM A995 6a is not listed in Table 1 of ASME B16.34-2004. Look at ASTM A351 instead for cast duplex stainless steel castings.
