There are differences, although the two materials are similar. ASTM A992 should be specified for all W-shapes used today.
It is similar to ASTM A572 Gr. 50, but has better controls on chemistry and mechanical properties. It includes minimum values for yield and tensile strengths, a maximum ratio for yield strength to tensile strength, and a maximum carbon equivalent value.
It is also less expensive than ASTM A572 Gr. 50 (and ASTM A36) for wide-flange shapes.
Note, however, that ASTM A992 is not currently used in the production of any shapes besides W-shapes.
When I was young I had marbles, some were steelies...I researched the projected tragectory compositions of both multiple glass and/vs steel marbles....at age 12.
If you belive this I can sell you an English Bridge located in Arizona.
