Your comments were what I was thinking, except I had never seen the A518.
A 496 material is the correct designation for the material used by the Nelson arc welding machines.
A 706 material would be acceptable for use, in lieu of A 496, if the contractor intended on providing all-around fillet welds to the structural steel (be prepared to give them an appropriate weld thickness schedule, and don't forget the visual inspection). Fillet welds work up to #6 or somewhere in there before your cross sectional area to circumference ratio makes it impossible to connect with fillet welds.
If you're on a small job, contractors sometimes seem to opt for welding the bars themselves rather than bringing in the specialty equipment for the DBAs.
A 518? From what I see this is an iron casting designation.
