FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgy, in particular to nickel-based superalloys which can be used in gas turbine details. The nickel-based superalloy contains, wt %: C≤0.1; Si≤0.2; Mn≤0.2; P≤0.005; S≤0.0015; Al 4.0-5.5; B≤0.03; Co 5.0-9.0; Cr 18.0-22.0; Cu≤0.1; Fe≤0.5; Hf 0.9-1.3; Mg≤0.002; Mo≤0.5; N≤0.0015; Nb≤0.01; O≤0.0015; Ta 4.8-5.2; Ti 0.8-2.0; W 1.8-2.5; Zr≤0.01; Ni - the rest.
EFFECT: alloy is characterised by high parameters of corrosion resistance and creep-resistance.
