FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgy field, particularly to manufacturing of heat-resistant high-quality steels with increased operational and mechanical properties, used in atomic energetics, for details of tracklaying and other machines, operating in radioactive area. Steel contains carbon, silicon, manganese, chrome, nickel, gadolinium and iron, at following ratio of components, wt %: carbon 0.2 - 0.6, silicon 0.8 - 1.5, manganese 0.4 - 1.0, chrome 22.0 - 25.0, nickel 12.0 - 15.0, gadolinium 0.1 - 0.25, iron is the rest.
EFFECT: there are improved mechanical and anti-radiative steel properties.
