FIELD: metallurgy.
SUBSTANCE: invention relates to nickel-base heat-resistant weldable alloys. Proposed nickel-base heat-resistant weldable alloy has the following chemical composition, wt.-%: carbon, 0.03-0.10; chrome, 20.0-32.0; molybdenum, 10.5-18.0; niobium, 2.5-4.5; aluminum, 1.0-1.0; tungsten, 0.3-3.0; vanadium, 0.1-1.0; boron, 0.0001-0.006; magnesium, 0.001-0.05; lanthanum, 0.001-0.10; cerium, 0.001-0.06, and nickel, the balance. Invention provides high indices of strength, ductility, thermal resistance and heat-resistance of alloy in combination with good values of weldability and deformability.
EFFECT: improved and valuable properties of alloy.
