*For Grade 1 and 6, each reduction of 0.01% C below 0.30%, an increase of 0.05 % Mn above 1.06 % would be permitted to a max. of 1.35%.
*For Grade 6, the limit for columbium may be increased up to 0.05 % on heat analysis and 0.06 % on product analysis.
*Generally, the carbon equivalent C.E = [C + Mn/6 + (Cr + Mo + V)/5 + (Ni + Cu)/15] shall not exceed 0.43% by heat analysis.
