According to TU 14-1-848-74 chemical analysis is presented for steel grade 14H20N25V5MB-P (LZHT-P), melted in a plasma-arc furnace with a ceramic crucible. The content of manganese is allowed to deviate ± 0.30%. At the request of the consumer, nitrogen is introduced into the steel by a calculation of 0.10-0.20% and is not determined by chemical analysis.
