In addition to the mechanical properties, are other pertinent information related to these classes of steel like room temperature impact and chemistry to determine which steels fall into a particular Class.

For Class 4
UTS 105 min Ksi
YS 85 min Ksi

For Class 8
UTS 105-125 Ksi
YS 85 Ksi min

YS reported at 0.02% offset.
