KHN75MBTJU - ЭИ602 round

KHN75MBTJU - ЭИ602 round


Round alloy KHN75MBTJU has considerable strength and reliability, intended for the production of parts that operate at high temperature (up to 850ºС) in aggressive chemical environments. Thanks to Nickel and chromium, fragments made of this alloy have high corrosion resistance, ductility and malleability, aesthetic appeal. The surface of the circle is not susceptible to oxidation during long-term operation at high temperatures. Plasticity makes it a popular instrument. It is resistant to oxidation, a nitrogen atmosphere, ammonia atmosphere. The main drawback — low resistance in the atmosphere of sulfur compounds. The disadvantages include considerable cost because of the high cost of the main components — Nickel.

Basic properties

The coefficient of linear expansion = 12.4 (1/deg) at a temperature of 100 °C. the Density of 8.3 g/cm 3, heat — 13.45 W/(m*deg). The coefficient of thermal conductivity of 0,126 • 102 W/(m • K). Thanks to a good chemical composition, it also has high weldability, which allows a variety of design technology without using special equipment and without additional heat treatment.


To impart additional hardness to the applied quenching at t º 1000 — 1100ºС with subsequent cooling in water or air. It promotes the normalization of internal stresses of the material, increasing the strength characteristics.


The successful combination of the components of the alloy, allows the use of round KHN75MBTJU in various fields of industry, manufacturing equipment for the metallurgical complex and details of furnaces for heat treatment, power stations. The chemical stability and strength, it is widely used in the production of prefabricated and welded structures for the equipment for the production of ammonia, petrochemical plants. This ensures trouble-free long operation of the structures within the operating temperature to 850 °C under high pressure.
