FIELD: metallurgy.
SUBSTANCE: proposed method comprises melting metal by electroslag method, accumulating the melt in crucible, melt deoxidising, modifying, microlloying and charging in casting mould by centrifugal forces. Melt is microalloyed by molybdenum, while deoxidising and modifying is performed by vanadium, rare-earth metals and/or alkaline-earth metals added to the melt in the following amount, in wt %: molybdenum - 0.05-0.2, vanadium - 0.01-0.1, rare-earth metals and/or alkaline-earth metals - 0.01-0.1.
EFFECT: higher physical properties.
