Yes, it applies only to AL-6XN. The Standard Specification of SB-691 applies to only UNS N08367 and N08366. The actual specification is titled "Specification for Iron-Nickel-Chromium-Molybdenum Alloys (UNS N08366 and UNS N08367) Rod and Bar".
SA-249/SA-249M Welded Austenitic Steel Boiler, Superheater, Heat Exchanger, and Condenser Tubes

Per your question, you are therefore comparing Tubes with Rod/ Bar/ Wires.
The spec. for AL6XN Tubes is ASME SA-249 (spec. common for AL6XN & 316L welded tubes)
The spec. for SS316L Rod, Bar, and Wire is SA 479.
