I've observed this for several years. Usually I give the contractor the option of using 40 grade steel for #4 bars and smaller though often, they end up being 60 grade. Small scale retailers like hardware stores seem to have mostly 40 grade, suitable for simple residential or small commercial construction. The one advantage to the lower 40 grade steel is when bending is required. A #5 bar 40 grade can be bent by hand, 60 grade becomes brittle and is harder to bend. Larger sizes require shop bending or a "hickey" in the field. That's my thoughts.
