HN68VKTYU vie alloy tube, circle
Steel brand HN68VKTYU-vi-vi EP578 is a superalloy based on nickel (62,5−69,8% Ni) and chromium (16−19%). Also, included in the composition of metals such as tungsten, cobalt, titanium, aluminum. Used for the production of conveyor furnace nets, rollers slot ovens ceramic firing. 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. This steel is used as a construction material for internal combustion engines, steam and gas turbines, in nuclear boilers.

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. Pipe made of steel grade HN68VKTYU vie gazootvedeniya used for industrial furnaces and nuclear boilers Such a pipe. It is a rather plastic product, making possible to build a pipe system at any angle. Metal has a rather attractive appearance and does not require a protective coating.
Forging products of alloy HN68VKTYU-vie 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 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.
