Stainless nickel alloys with high heat resistance characteristics have long and effectively been used for the needs of all branches of the modern industrial complex. Despite the high price of nickel, materials with its high content with its unique working qualities completely compensate for the initial costs, ensuring long-term reliable operation of the entire equipment complex.


The alloy of the brand ХН80ТБЮ compares favorably with many similar materials with increased resistance to high temperature conditions during operation. Most often, products from it are used in the manufacture of turbine mechanisms, the temperature in the working zone of which does not exceed seven hundred degrees Celsius. In addition, this material is very resistant to high loads during operation, which is also important for turbine blade blades. An additional advantage of an alloy of this type is the resistance to the effects of gaseous media. After all, the main danger of destruction during the operation of turbine elements lies precisely in the corrosion of the gas type, which causes the loss of strength of the material along the grain boundaries that form the structure of the raw materials. Therefore, the alloy KhN80TBYu successfully combining a lot of useful and popular qualities of this kind, is simply indispensable for aircraft building and machine building.

Technological parameters

Weldability Necessary operations
The material refers to the type of alloys difficult to weld Before welding, the contacting surfaces are heated to two hundred or three hundred degrees. After welding, to improve the characteristics of the seam zone, the semi-finished product undergoes high-temperature annealing.
