What exactly is the difference between SA-105 and SA-266 Cl. 2 forgings? We are fabricating a replacement vessel that originally had SA-105 flanges, but the customer would like to use SA-266-2 instead.

Of course SA-266 Cl.2 is allowed under Section VIII Div.1.
The two materials are quite equivalent in my opinion: only minor differences in the specification (heat treatment policy for instance).
I think the choice is a matter of taste, or, better said, of continuity at client's organisation.

I remember these two grades as generally used for flanges and other applications like tube sheet etc., On the former, there is a max limit in weight of 10000 lbs (this is old, rusty recollection of mine, I am not sure what the current code says...) Sorry if I have mislead anyone with this...
