FIELD: metallurgy.
SUBSTANCE: invention can be used for manufacture of corrosion-resistant pipes, housings, evaporators and other welded units and parts to be operated in aggressive oxidizing media, in particular, chloride, such as KCl-AlCl3, at temperatures up to 650°C. Corrosion-resistant nickel-based alloy comprises, wt %: chromium 28-30, molybdenum 8-10, nitrogen 0.005-0.1, aluminium 0.1-0.3, carbon 0.004-0.01, silicon 0.001-0.05, iron not more than 0.5, manganese not more than 0.25, lanthanum 0.002-0.05, nickel and impurities 61-63.
EFFECT: alloy with improved physical, mechanical and operational properties: structural stability in chloride media in a temperature range of 500-650 degrees, ductility, corrosion resistance, including resistance to local types of corrosion, with good formability and weldability values.
