ХН75ТБЮ, ЭИ869 round, wire, tube, sheet, strip


Generally, alloys based on Nickel, despite its relatively high cost, have a set of unique properties that compensate for the initial costs. Such properties include high corrosion resistance on the background of good machinability of the material, a significant resistance, allowing the use of articles made of Nickel alloys under the impact of the Assembly to elevated temperature regimes. So today, materials of this type are deservedly gained increased popularity and constant demand in many industries in connection with which their trade is constantly usovershenstvuetsya and growing.


The basic properties of a material such as alloy ХН75ТБЮ directly depend on the chemical composition, the percentage content of the constituent elements. So Nickel has led to the inertia of the steel to the action of aggressive industrial environments and high heat resistance, preventing the destruction of this alloy under the action of high temperature modes of operation. These useful qualities have determined the scope of application of this alloy. Made a different attachment, rotary members, a flat spring type, the details of the combustion chamber and the constructive part of the pipeline systems, whose work is limited to temperature index of 950 degrees Celsius. Another important feature is the good weldability of the alloy in connection with which the semi-finished products of the brand ХН75ТБЮ can be used for the manufacture of welded structures of any complexity.

Technological parameters

Weldability The necessary operations
The material is of type alloys difficult to weld Before welding contact surface has warmed up to two hundred or three hundred degrees. After welding, to improve the characteristics of the suture zone of the prefabricated subjected to high temperature annealing.
Alloys limited welded type Qualitative welded connection, maybe get after preheating contacting surfaces to one hundred or one hundred and twenty degrees Celsius, and conducting a final heat treatment suture zone, after the completion of welding works
Raw materials, not having restrictions on welding Prior training is not required for high-quality welding
