Sheet, round, wire ХН68ВКТЮ - ЭП578
Steel brand ХН68ВКТЮ-ЭП578 VI-VI is a heat-resistant alloy based on Nickel (the 62.5 69.8% in Ni) and chromium (16−19%). In addition, the structure includes such metals as tungsten, cobalt, titanium, aluminum. Used for the production of furnace conveyor nets, rollers slot furnaces firing of ceramics. Pipe from this steel can serve as a detail burner. It is used for the manufacture of covers of thermoelectric converters, because it does not pollute the electrodes thermocouples and ensures a good protection of the thermocouple wire when working in aggressive environments and under hazardous conditions. The pipe can withstand temperatures of about 1250−1300°C for a long time and have high resistance to loads at high temperature. This steel is used as structural material for internal combustion engines, steam and gas turbines, nuclear boilers.

Resistance to gas and air corrosion at very high temperatures makes it relevant to the application of the alloy in a variety of heating devices and power systems, which requires elements with high resistance. The alloying of aluminum and silicon helps to withstand exposure to aggressive environments, because when heated, these substances form on the surface protective film — oxides of aluminum, chromium and others. The pipe of steel grade ХН68ВКТЮ-VI gas outlet is used for industrial furnace and nuclear boilers Such pipe. is a rather a plastic product, making possible to build the pipe system at any angle. The metal has quite attractive look and doesn’t need protective coating.
Forging products of alloy ХН68ВКТЮ-VI is carried out at a temperature of about 1150−1180°C at the beginning and not less than 850 °C at the end of the process. Tempering is performed in air or in water at temperatures up to 1200 °C. the Alloy refers to an easily welded, welding can be accomplished in any way. For manual arc welding use specialized electrodes OzL-25 and OzL-35.
