FIELD: metallurgy.
SUBSTANCE: invention relates to the field of ferrous metallurgy, namely, to the composition of steels used for the manufacture of the hot-deforming tool and the details of the thermal aggregates. Steel contains, mass%: carbon 0.2–0.3; manganese 3.5–3.8; silicon 0.8–1.2; chromium 4.5–5.5; calcium 0.001–0.002; titanium 0.01–0.02; yttrium 2.6–3.0; silver 2.2–2.6; tungsten 3.0–3.6; rest being iron.
EFFECT: heat resistance of the steel is improved.
