HN68VMTYUK EP693-VD-VD alloy tube, circle
Steel grades HN68VMTYUK-tm (EP693-VD) is melted in electric arc furnaces. It is a superalloy based on nickel (as a part of its order of 68%), followed by content — chrome. Doped alloy metals such as tungsten, molybdenum, titanium, aluminum, cobalt. Hot forging products is carried out at a temperature of about 1150−1180 ° C at the beginning and at least 850 ° C at the end of the process. Tempering is carried out in air or water at a temperature up to 1200 ° C. Fusion refers to easy welded, welding can be performed in any manner. For manual arc welding are used RLA-25 special electrodes and RLA-35.
Production of conveyor furnace nets, rollers slot ovens ceramic firing. This steel is used as a construction material for internal combustion engines, steam and gas turbines, in nuclear boilers. of the steel pipe can be part of the burner. It is used for the manufacture of covers of thermoelectric converters, because It does not pollute the thermocouples and electrodes ensures good protection in the case of thermocouple wire operation in hostile environments and harmful conditions. Pipe withstands a temperature of about 1250−1300 ° C for a long time and have a high resistance to stress at a high temperature.
Resistance to corrosion of the gas and air at high temperatures makes it necessary to use an alloy of various heating devices and power plants, in which the elements are required with high resistance values. Doping of aluminum and silicon help withstand corrosive environments, since these substances when heated to form a protective coating film — aluminum oxides, chromium and others. The tube of this brand is used for gazootvedeniya industrial furnaces and nuclear boilers. It is quite malleable, making possible to build a pipe system at any angle. Metal has an attractive appearance and does not need a protective coating.
