HEAT-PROOF RESISTANT WELDED ALLOY ON THE BASIS OF NICKEL AND THE PRODUCT MANUFACTURED OUT OF THIS ALLOY Russian patent published in 2007 - IPC C22C19/05 

FIELD: metallurgy industry; aircraft industry; mechanical engineering; other industries; production of the heat-proof resistant welded alloys on the basis of nickel used for manufacture of the heat-resistant pipes, the gas collectors, the screens and other details and the welded blocks.

SUBSTANCE: the invention is pertaining to the field of metallurgy of the heat-proof resistant wrought welded alloys on the basis of nickel and may be used for manufacture of the heat-resistant pipes, the gas collectors, the screens and other details and the welded blocks of the aircraft engineering, mechanical engineering and other branches of the national economy operating at the temperatures up to 1100°С. The invention presents the heat-proof welded alloy on the basis of the nickel of the following ratio of the components (in mass %): cobalt - 26.0÷30.0; chromium - 20.0÷23,0; Carbon - 0.02÷0.07; tungsten-13.0÷16.0; aluminum - 0.01÷0.30; niobium - 0.5÷1.0; lanthanum - 0.003÷0.06; magnesium - 0.002÷0.03; vanadium - 0.1÷0.6; neodymium - 0.002÷0.03; cerium - 0.01÷0.3; yttrium - 0.001÷0.05; nickel - the rest. The technical result of the invention is the improved characteristics of the high-temperature strength, the high-temperature resistance, the heat stability, the technical pliability, and first of all - the deformability and weldability.

EFFECT: the invention ensures the improved characteristics of the high-temperature strength, the high-temperature resistance, the heat stability, the technical pliability, and first of all - the deformability and weldability.
