FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgy field and can be used in aerospace industry for receiving of heatproof corrosive alloy on the basis of nickel for manufacturing of product, operating in hostile environment long time at temperatures 550-800 °C. It is proposed heatproof alloy on the basis of nickel. Alloy contains, wt %: carbon 0.025-0.035, boron 0.015-0.025, zirconium 0.015-0.025, chrome 11.2-11.5, cobalt 14.7-15.0, molybdenum 3.3-3.5, aluminium 3.75-3.95, titanium 5.0-5.2, tantalum 1.9-2.1, tungsten 0.5-0.7, niobium 0.05-0.25, hafnium 0.15-0.25, manganese 0.10-0.20, nickel - the rest. Total content of titanium and aluminium is 8.8-9.1 wt %, ratio of titanium to aluminium is 1.32-1.36 wt %, and total content of hafnium and niobium is 0.25-0.35 wt %.
EFFECT: development of heatproof alloy on the basis of nickel.
