(OP)
Does anyone have any experience using A 276, 316 SS as a vessel component. We are fabricating a piece of our vessel from bar stock, but the ASME II tables have no information (that I've found) for A 276. We're using it at 1200 F and 4500 psi.
Any experience? References?
Thanks.

If your "piece" of the vessel is a pressure retaining component, then as metengr stated, you may not use the SA276 material. On the other hand, if the piece is a clip or ring or support etc then you may use it. But... you'll have to decide for yourself what the allowable stress will be.

The difference between SA-276 and SA-336 has more to do with differences in melting practice and heat treatment specifications. I would recommend that you review and compare these specifications.
From your last post, it sounds like you had purchased this material and have already made plugs. If this is the case, replace this material with SA-336.
