According to TU 108.13.43-89, the chemical composition of the charge blanks from VX4LM alloy is given. Zirconium and boron are introduced into the metal by calculation and chemical analysis are not determined. Additive of hafnium, calcium and cerium in the amount of 0.010% of each element is allowed. These elements are not analyzed, but are entered in the certificate. The content in the metal of copper is limited to 0.10%, lead - 0.0010%, bismuth - 0.00050%.
