Ni is the basis.
According to TU 14-1-4828-90, the chemical composition is given for the alloy grade KhN57KVYUTMBL-VI (Chs88-VI). Boron, zirconium, yttrium and cerium are introduced into the metal by calculation and chemical analysis are not determined. It is possible to estimate the mass fraction of arsenic in points on the scale of spectral analysis - the mass fraction of arsenic should be no more than 1 point.
