According to TU 14-1-2479-78, the chemical composition is given for steel grades ХН56ВМТЮ-ВД (ЭП199-ВД), ХН56ВМТЮ (ЭП199). Boron is introduced into the metal by calculation and chemical analysis is not determined. Provided that all other requirements are met, the metal is allowed to deviate by chromium minus 0.5%. The metal is injected with magnesium in an amount of no more than 0.05% by calculation and chemical analysis is not determined.
