Metallurgy under pressure is one of the main trends in the development of quality metallurgy. High-nitrogen steel of responsible purpose for special engineering was created and produced on the basis of metallurgy under pressure by the methods of special electrometallurgy. Comparative mechanical tests of high-nitrogen steel were carried out. The structure of the steel was analyzed by the methods of non-destructive testing. High nitrogen steel was found to meet the technical requirements. The structure is dense, without defects.

We have carried out researches for working out technological electroslag remelting conditions to produce bimetallic ingots. A new plant flow diagram has been developed for the manufacture. Experimental series of melting was performed on a laboratory electroslag remelting installation by developed by us electroslag remelting conditions. Bimetallic ingots for armour were produced of different combinations steel grades. Ingot of X38CrMoV 5 1 (DIN 1.2343; AISI H11) -10G2SF perspective steel grades is investigated. By the method of non-destructive testing the fusion of two steel grades along height of ingot is investigated. Macrostructure of cast transverse templates is investigated. A complete fusion of steels is established.
