  • the application limits, which have the previous GJS alloy can be overcome.
  • the iron-based alloy according to the invention has high elongations for the range of application in the temperature range of 450 ° C - 550 ° C and has the following composition (in wt .-%): Silicon (Si) 2.0% - 4.5%, Carbon (C) 2.9% - 4.0%, Niobium (Nb) 0.05% - 0.7%, Molybdenum (Mo) 0.3% - 1.5%, optional Cobalt (Co) 0.1% - 2.0%, Manganese (Mn) ⁇ 0.3%, Nickel (Ni) ⁇ 0.5%, Magnesium (Mg) ⁇ 0.07%, Phosphorus (P) ⁇ 0.05%, Sulfur (S) ⁇ 0.012%, Chrome (Cr) ⁇ 0.1%, Antimony (Sb) ⁇ 0.004%, Rest iron.
  • the proportion of silicon, cobalt, niobium and molybdenum is ⁇ 7.5% by weight, in particular ⁇ 6.5% by weight.
  • Niobium improves creep strength with consistently high LCF strength and good toughness.
  • Niobium causes a higher heat resistance due to the precipitation of finely distributed Nb carbides, whereby the application limits are shifted to high temperatures.
  • Cobalt causes a solid solution which positively influences the properties of the alloy at high temperatures and low stresses.
  • the proportion of cobalt in the alloy is between 0.5 wt% to 1.5 wt%.

Associated with the steam inflow region 333, the turbine shaft 309 has a radially symmetrical shaft shield 363, a cover plate, on the one hand for dividing the steam flow into the two flows of the medium-pressure turbine section 303 and for preventing direct contact of the hot steam with the turbine shaft 309.
  • the turbine shaft 309 has in the medium-pressure turbine section 303 a second blading area 366 with the medium-pressure blades 354 on. The hot steam flowing through the second blading area 366 flows out of the medium-pressure turbine section 303 from a discharge connection 369 to a downstream low-pressure turbine, not shown.
  • the turbine shaft 309 is composed for example of two partial turbine shafts 309a and 309b, which are fixedly connected to one another in the region of the bearing 318.

  • the compressed air provided at the turbine-side end of the compressor 105 is supplied to the burners 107 where it is mixed with a fuel.
  • the mixture is then burned to form the working fluid 113 in the combustion chamber 110.
  • the working medium 113 flows along the hot gas channel 111 past the guide vanes 130 and the rotor blades 120.
