Abstract
The subject of the solution consists in stable austenitic precipitationally hardenable steel, which satisfies the needs for material for rotors of cryoturbogenerators more than other known materials. The steel is characteristic by advantageous combination of mechanical and physical properties in the whole temperature range, i.e. from 300 to 4.2 K. The steel is weldable, formable and workable, and it is possible to produce large-size forged pieces from it. It contains from 0.01 to 0.05 percent by weight of carbon, from 13 to 16 percent by weight of chromium, from 22 to 34 percent by weight of nickel, from 1.6 to 2.8 percent by weight of titanium, from 0.1 to 0.4 percent by weight of aluminium, from 0.1 to 0.4 percent by weight of vanadium, traces to 1.2 percent by weight of manganese, traces to 0.3 percent by weight of silicon, traces to 0.01 percent by weight of sulphur, and traces to 0.01 percent by weight of phosphorus. The principle of the solution consists in the fact that the average contents of Ni/(Ti+Al) in percent by weight is higher than 9 and that it also contains from 1.5 to 2.6 percent by weight of molybdenum, all counted in per cent by weight.
