a For each reduction of 0.01 % below the specified carbon maximum, an increase of 0.06 % of manganese above the specified maximum will be permitted up to a maximum of 1.35 %.

b Unless otherwise specified by the purchaser, for each reduction of 0.01 % below the specified carbon maximum, an increase of 0.06 % of manganese above the specified maximum will be permitted up to a maximum of 1.65 %.

c The sum of Chromium, Copper, Molybdenum, Nickel, and Vanadium shall not exceed 1 %.

ASTM A106 Grade B steel pipe has a maximum carbon equivalent (CE) of 0.5.
CE = C + Mn/6 + (Cr + Mo + V)/5 + (Ni + Cu)/15
