general characteristics

The accessory of the brand ХН77ТЮР to the group of chromium-nickel materials allows to use it for manufacturing parts operating under the most severe conditions. The percentage of nickel in the alloy can vary from 70 to 77.4 percent, and the proportion of chromium is 19−22 percent. To increase the operating parameters, the material is doped with additives of silicon, aluminum, titanium, cerium and some others. Due to the optimal technological and operational parameters, such material copes with the hardest work and actively opposes the influence of most harmful industrial factors, ensuring the reliability and durability of the operation of important equipment.

Nickel in the composition of the tape ХН77ТЮР provides a sufficiently high plasticity of semi-finished products, which facilitates its processing and installation. This tape has a high resistance to corrosion and considerable heat resistance, which makes it possible to use it in operation at elevated temperatures and presence of an aggressive medium.

Application of

The blades of gas turbine engines, fasteners designed for use at operating temperature, up to 750ºC are manufactured from the tape ХН77ТЮР. The tape ХН77ТЮР is used at manufacturing of cars, for manufacture of elements of the raised durability intended for work at vibration and the maximum loading. Given the high rate of hygiene of raw materials it is widely used in the manufacture of surgical instruments. A high specific resistivity makes it possible to use the alloy in the production of heating and measuring devices. In addition to the industrial sphere, a durable and beautiful alloy has proven itself in everyday life. Original decorative ornaments and beautiful metal tableware have long become an attribute of our daily life.

Buy at the best price

Acceptable cost of the tape ХН77ТЮР and a wide range of products will allow any buyer to choose the option that most fully satisfies any requests. High quality of manufacturing and full conformity of production to requirements of the state standard documentation and technical conditions for delivery — that basic criterion which our company adheres in work with clients.
