FIELD: metallurgy.
SUBSTANCE: invention relates to a steel which can be used for the manufacture of a hot-deforming tool. Steel contains 0.15–0.25 wt.% of carbon, 0.15–0.25 wt.% of silicon, 0.5–1.0 wt.% of manganese, 4.5–5.5 wt.% of chromium, 0.003–0.008 wt.% of calcium, 0.1–0.15 wt.% of titanium, 0.01–0.03 wt.% of yttrium, 4.3–4.8 wt.% of hafnium, 0.15–0.25 wt.% of aluminium, 0.1–0.15 wt.% of niobium and rest iron.
EFFECT: improved heat resistance of steel is ensured.
