Dignity

Wire ХН78Т is actively used in many spheres of human life from the needs of the industrial complex to the manufacture of household appliances and elements of modern decor. Anticorrosive resistance to many aggressive factors, the ability to withstand the destructive influence of high temperatures in the work area, manufacturability and good machinability — this is the list of the most important qualities of the HN78T wire .

COMPOSITION

Wire ХН78Т has an excellent combination of basic and auxiliary alloying substances in the composition.

APPLICATION

More often, the wire ХН78Т is used for the needs of the machine-building and aviation industries, as well as in the power complex and in the production of welding electrodes for connecting structural elements made from other nickel-containing alloys. Given the good weldability of semi-finished products from a similar material, they are actively used in the manufacture of metal structures of any shape and complexity. It is important to note that although such an alloy does not require preliminary preparation of the surface of the semi-finished product before welding, but in some particularly important cases, to ensure high strength of the joint, the structural elements are heated to two hundred or three hundred degrees. The suture zone is then heat treated to relieve the residual stresses after the welding procedure is completed.
