Composition brand HN70YU
The main component of the alloy — nickel up 71.2% of the total. To 29% (when the proportion of nickel in the alloy is less than 71%) took the chrome. This brand has a high heat resistance is not only due to chromium and nickel, but also due to additives of silicon and aluminum. These substances are capable of forming a high temperature oxide film, which creates additional protection product, can therefore be used in various high temperature installations. The silicon contained in the alloy in an amount of not more than 0.8%, and aluminum — from 2.8 to 3.5%. Also, the alloy contains approximately equal amounts of barium and carbon — 0.1% manganese — up to 0.3% phosphorus — up to 0.015% selenium — up to 0.03% copper — 0.07%.

HN70YU alloy produced in induction furnaces or open way ESR. Production is regulated by GOST 12 766.4−77 and 5632−72. The first one sets the standards for long products of steel with a high electrical resistance, normalizes the second corrosion-resistant heat-resistant high alloys. Making rod HN70YU submits technical specifications 14−1-1497−75 conditions, and wire work — GOST 12 766.1−77. Semi-finished steel that is used in the manufacture of parts of the combustion chambers, pockets, diffuser screens afterburners and intended for the temporary increase in engine thrust. These parts can be operated at t ° 1100−1200 ° C and withstand a large enough load.
Forging metal is produced at t ° 1150- 900 ° C at the beginning and end of the process, respectively. Ready rod quenched in air at t ° 1200 ° C. The wire passes quenching in air at a lower temperature — 1000 ° C. As the steel of this grade is limited to welding, after welding products are recommended to be heat treated to achieve the elimination of residual stress.
