FIELD: metallurgy.
SUBSTANCE: proposed refractory nickel based alloy comprises the following components in wt %: carbon 0.005-0.12; chrome 11.5-12.4; cobalt 8.0-8.7; tungsten 6.7-7.4; molybdenum 0.25-0.55; titanium 4.0-4.2; aluminium 3.9-4.2; boron 0.001-0.012; manganese ≤0.12; silicon ≤0.10; niobium 0.8-1.0; magnesium ≤0.12; calcium ≤0.12; copper ≤0.05; iron ≤0.1; sulphur ≤0.005; phosphorus ≤0.005; nitrogen ≤10.0 ppm, oxygen ≤10.0 ppm, nickel - rest, at that ration between titanium and aluminium is 0.95-1.07.
EFFECT: alloy is characterised with increased long-term strength in combination with high corrosion resistance, high structural stability for service life.
