The material with the marking ХН50ВМТЮБ-ви refers to the type of nickel high-temperature alloys. This raw material is recommended to be used for the manufacture of products, the operating temperature of which does not exceed nine hundred and fifty degrees (with limited time operation mode). High stability not only to high-temperature operation modes, but also to significant loads significantly increases the scope of their application. This alloy is used in the production of various parts such as flanges or fittings and other semi-finished products experiencing high loads during the performance of their functions.


A sufficiently high content of nickel determines the good stability of the alloy to the action of a gas or liquid aggressive medium. The ability to resist fatigue processes for a long time, when working under the influence of high loads determines the durability and reliability of operation of semi-finished products of this type. However, poor weldability limits the use of such an alloy in the formation of welded structures. Welding of steel ХН50ВМТЮБ-ви requires preliminary preparation. Due to good performance indicators, such alloy is easily processed by cutting or forging. Hot working begins at a temperature of about one thousand one hundred and seventy degrees and ends at 850 ° C by the end of the forging procedure.
