Alloying increases the technological properties of steel: heat resistance and heat resistance, the ability to withstand aggressive environments. The start temperature for forging semi-finished products is 1170 °C, and the end temperature is about 850 °C. Hardening is carried out in air, hardening temperature 1050−1150°C.


Heat-resistant and heat-resistant pipe 20X25H20S2, AISI 314, EI283 is resistant to corrosion in air and in hot gas environments. Such a pipe, alloyed with chromium, nickel, silicon, molybdenum, vanadium, tungsten, is able to withstand contact with an aggressive environment for a long time, because during the heating process, alloying substances form protective oxide films on the surface that prevent rusting. Heat-resistant and heat-resistant steel 20X25H20S2, AISI 314, EI283 is quite plastic, which allows producing the most complex structures from it. The metal has an attractive appearance, does not require painting.


Production of conveyor furnace grids, rollers of slotted furnaces for high-speed firing of ceramic tiles, household ceramics and other ceramic products. The pipe heat-resistant and heat-resistant 20X25H20S2, AISI 314, EI283 is used in the details of the burner. It is used in the manufacture of covers for electrical thermocouples, because it does not contaminate thermocouple electrodes and guarantees reliable protection of the thermocouple when operating in an aggressive environment. Such a pipe can withstand temperatures of 1000 °C for a long time, has high creep resistance under load. It is used for furnaces of steam and gas turbines, jet engines, nuclear power plants as a structural material.
