FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgy, namely to a nickel-based wrought alloy with high creep resistance and long service life and can be used as material for precision parts of hot part in space rocket engine or for precision parts of hot part in gas turbine. Wrought heat-resistant nickel-based alloy contains the following, wt.%: C from 0.04 to 0.08, Cr from 18.50 to 21.50, Co from 9.00 to 11.00, Mo from 8.00 to 9.00, Al from 2.00 to 3.00, Ti from 1.10 to 1.49, Nb from 0.81 to 2.00, B from 0.003 to 0.009, Sc from 0.001 to 0.10, Zr not more than 0.02, the rest is nickel and non-removable impurities, while the weight percentage of Al, Ti and Mo in the alloy satisfies condition 11.59 ≤ Al + Ti + Mo ≤ 13.0.
EFFECT: alloy is characterized by high creep resistance and long service life.
