Dignity

Anticorrosive resistance to many aggressive factors, the ability to withstand the destructive effect of high temperatures in the work area, manufacturability and good workability — this is the list of the most important useful qualities of the tape KhN78T. An excellent combination of basic and auxiliary alloying materials in the composition explains its popularity and active application in many areas: from the industrial complex to the manufacture of household appliances and elements of modern design for the arrangement of residential and office premises.

composition

Virtually all the advantages of the tape ХН78Т are due to its optimally selected chemical composition.

APPLICATION

The variety of products produced from the tape KhN78T and a wide range of standard sizes can satisfy any customer requirements and choose the necessary option for solving the most complex engineering problem. Most often the tape ХН78Т is used for the needs of machine-building, aviation industry, energy complex. Given the good weldability of the tape HN78T, it is 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.
