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 .


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

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.


On our site we offer a wide range of products from chromium-nickel alloys. High quality products and the absence of intermediaries determine the most favorable conditions for the acquisition of wire ХН78Т for solving any production problems. Delivery in the shortest time in any region of the country and abroad, the compliance of products of regulatory documentation has long won the trust of regular customers. Due to the reasonable cost and a wide range of semi-finished products, chromium-nickel alloys enjoy constant popularity in all spheres of production.
