FIELD: metallurgy. SUBSTANCE: nickel-base composition has the following components, wt. -%: aluminium, 7.8-9; cobalt, 3.5-4.5; titanium, 0.6-1.2; tungsten, 1.8-2.5; molybdenum, 4.5-5.5; chrome, 4.5-5.5; carbon, 0.007-0.02; lanthanum, 0.0015-0.015; and nickel, the balance. Alloy exhibits the enhanced resistance to hot (sulfide) corrosion, high resistance to fatigue at contact with alkaline metal salts, for example, NaCl, NaSOor their mixture. EFFECT: enhanced quality. |
