According to TU 14-1-3617-83 the chemical composition is given for alloys of grades ХН43БМТЮ-ВД (ЭП915-ВД) and ХН43БМТЮ-ИД (ЭП915-ИД). Cerium and calcium are administered by calculation and chemical analysis is not determined.
According to TU 14-1-4155-86 the chemical composition is given for alloys of grades ХН43БМТЮ-ВД (ЭП915-ВД) and ХН43БМТЮ-ИД (ЭП915-ИД). Cerium and calcium are introduced into the metal by calculation and chemical analysis is not determined. In the finished metal, deviations in chemical composition are allowed: for carbon ± 0.010%, for molybdenum +0.20%, for titanium ± 0.10%. The permissible residual copper content is not more than 0.25%, tungsten - not more than 0.20%. Calcium is introduced into the metal when melting in open furnaces.
