FIELD: metallurgy.
SUBSTANCE: invention can be used as material for manufacture of welded high-loaded parts of gas turbine engines with operating temperature of up to 600°C, which work in conditions with increased requirements for gap stability. There proposed is heat-resistant wrought alloy containing the following, wt %: carbon 0.02÷0.08, cobalt 18.0÷25.0, iron 22.0÷30.0, chrome 0.3÷1.2, tungsten 0.05÷2.0, molybdenum 0.05÷2.0, tantalum 0.1÷2.0, aluminium 0.3÷0.8, titanium 1.5÷2.7, niobium 4.5÷5.5, boron 0.005÷0.010, lanthanum 0.001÷0.03, cerium 0.001÷0.03, magnesium 0.003÷0.03, scandium 0.003÷0.03, nickel - the rest.
EFFECT: alloy is characterised with high strength properties, long-term strength and low linear expansion coefficient and weldability.
