Please don't use all capitals. It's interpreted as SHOUTING!!!
You need to know what steel you're talking about API??, ASTM ????
Then look up the properties for that grade and type of steel.
If its API 5L,grade A is a lower SMYS than Grade B(35,000 psi).
Also look at ASME B 31.3 - you'll find most of the data you want there.
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

Many years ago API tried to eliminate Grade A from 5L as no committee "users" used it . But the mills reported that there was still use in the "3 rd world" so it remained in the spec.
Tensile and Yield Strength (PSI) e.g. ASTM A106 Gr.A 48K & 30K, Gr.B 60K & 35K, Gr.C 70K & 40K. There is also corresponding difference for longitudinal and Transverse Strip Tests.
Higher Yield Strength will result in a thinner calculated wall thickness.
