I just finished (actually am still working on) the design of a SCBF and
pondered the same question. I talked with the contractor and am using 50
ksi steel. There is also a big advantage to using 50 ksi when it comes to
the weld size. See my post regarding weld size for more info.

Subject: Steel Plate Availability
I have some large industrial steel structures that will be utilizing Special
Concentric Braced Frames. The bracing gusset plates will be given special
design attention and I would like to keep the thickness down by using 50 ksi
plate. Is 50 ksi plate readily available in the 3/8 inch through 1 inch
OR should I keep life simple and just stay with A36 plate??
