Production

Steel grades ХН68ВМТЮК-VD (ЭП693-VD) is smelted in electric arc furnaces. Is heat-resistant alloy based on Nickel (it is composed of about 68%), followed by the content chrome. Alloy alloyed with such metals as tungsten, molybdenum, titanium, aluminum, cobalt. Hot forging products 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.

Application

Production of conveyor furnace nets, rollers slot furnaces firing of ceramics. This steel is used as structural material for internal combustion engines, steam and gas turbines, nuclear boilers. 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.

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. Pipe of this brand is used for gas outlet of industrial furnaces and nuclear boilers. It is quite plastic, and thus helped to build the pipe system at any angle. Metal has an attractive look and doesn’t need protective coating.
