Steel pipes HN73MBTYU-tm (EI698-VD) is made of heat-resistant nickel-based alloy. The composition comprises 65.073 — 71.2%. Ni, 26−29% Cr — refers to the chrome-nickel. Doped alloys. When melting the starting material are added to a variety of substances — metals and nonmetals affecting the quality of the final product. The aluminum used as additives — 2.8−3.5%, iron — 1%, barium — less than 0.1%, silicon — 0.8% manganese — 0.3% Ce — about 0.03% phosphorus — less than 0.015%, copper — about 0.07% and sulfur — about 0.012%. Smelted in an open induction furnace and electroslag remelting method is used — method for producing metal by means of melting in the bath conductive slag under the influence of an electric current. This method of melting considerably increases the quality of the metal. steel forging is carried out at a temperature from 1150 ° C at the beginning and 900 ° C — at the end of the process. After forging desirable quenching in water or in the air at t ° 1100−1200 ° C.
The percentage of (GOST 5632−72)
Fragments of pipeline systems operating at normal load. Pipes can have long used at temperatures of about 800 ° C, can withstand short-term heating to t ° 1200 ° C, above which nazhinaetsya active formation of scale. This alloy and zharoprochen zharostoek but unstable in environments containing sulfur.
Bars and terms can be used as a blank for the manufacture structural shapes, beams, angles, channels, or profile, special purpose which are used in the construction work of any complexity. The circle is used as a preform for manufacturing axes pushers, shaft and other moving parts of machinery. Weldability limited needs preheating to 200 ° C and a final heat treatment. The alloy used in the manufacture of heating elements, welding wire for welding of steel structures, welding parts in mechanical engineering. This alloy produces parts afterburner — additional combustion chamber of the turbojet engine, necessary to temporarily increase the thrust, as well as combustion chambers operating at a very low load at t ° 1100−1120 ° C.
Along with its gas pipeline system, pipes HN73MBTYU-tm can be used to remove water vapor, incandescent industrial gases and smoke. When heated, aluminum and chromium in the alloy composition forms an oxide film, increasing the degree of resistance to aggressive media material.
