a. Elements not included in this table shall not be intentionally added to the steel without the agreement of the purchaser, except for elements which may be added for finishing the cast. All appropriate measures shall be taken to prevent the addition of undesirable elements from scrap or other materials used in the steelmaking process.
b . The content of these elements need not to be reported unless intentionally added to the cast.
c. V may be replaced by Nb or Ti percent for percent provided that the V content shall be at least 0,05 % and the sum V + Nb + Ti is ≤ 0,21 %. d Additions of Nb, V or Ti are permitted and left at the discretion of the manufacturer. The content of these elements shall be reported
