FIELD: metallurgy.
SUBSTANCE: invention relates to ferrous metallurgy, in particular to cast iron compositions, which can be used to manufacture parts of thermal units. Cast iron contains, wt %: carbon 3.2–4.5; silicon 1.2–1.8; manganese 1.7–2.6; cerium 0.05–0.1; aluminum 1.5–2.5; hafnium 0.9–1.3; nickel 1.0–1.5; copper 1.7–2.3; vanadium 0.25–0.35; silver 0.005–0.01; iron – the rest.
EFFECT: technical result is higher heat resistance of cast iron.
