Ni is the basis.
According to TU 14-1-4739-89 the chemical composition is given for the alloy ХН57ВМТЮБЛ-ВИ (ЧС91-ВИ). Mass fractions of boron and zirconium are calculated. In agreement with the customer, deviations from the specified standards of chemical composition are allowed. Additives are added cerium, magnesium, barium, yttrium, calcium in the alloy in an amount of not more than 0.010% of each element by calculation. Mass fractions of boron, zirconium, cerium, magnesium, barium, yttrium, calcium are not determined by chemical analysis, but the calculated data are recorded in the certificate. Deviations are allowed for silicon and manganese with a total mass fraction of silicon and manganese not more than 0.60%.
