*Ar gyfer Gradd 1 a 6, byddai pob gostyngiad o 0.01% C o dan 0.30%, cynnydd o 0.05 % Mn dros 1.06 % yn cael ei ganiatáu hyd at uchafswm. o 1.35%.
*Ar gyfer Gradd 6, gellir cynyddu'r terfyn ar gyfer columbium hyd at 0.05 % ar ddadansoddi gwres a 0.06% ar ddadansoddi cynnyrch.
*Yn gyffredinol, ni fydd y cyfwerth carbon CE {{0}} [C + Mn/6 + (Cr + Mo + V)/5 + (Ni + Cu)/15] yn fwy na 0.43% yn ôl dadansoddiad gwres.
