ХН55МБЮ-VD, ЭП666 round, wire, tube, sheet, strip

Steel based on Nickel and iron brand ХН55МБЮ-VD has a high rate of heat resistance. This property of the material demanded in manufacture of gas turbine equipment and various piping systems used in the energy industry for thermal and nuclear power plants. Currently, such material is available quite extensive range of products from rolled plates, hot rolled to tubular blanks, forgings and bar stock.


The main parameters of the material resulting from the requirements of parts of turbine equipment. In this regard, the alloy ХН55БЮ-VD is quite flexible, able to withstand the fatigue processes, there is little cyclic and thermal in nature and has a high degree of inertia in relation to the action of gaseous corrosive environments. Because it is gas corrosion is the greatest danger when working turbine of the engine, provoking the reaction of weakening at the grain boundaries of the phase structure of material. Normalized operating temperature for semi-finished products made of an alloy of this type is nine hundred degrees Celsius (with a limited working time), and the values of the air temperature, to avoid the intensive scale formation on the material surface should not exceed one hundred degrees.
