Components for steam turbine




We present castings from our foundry, which are mainly used in the energy industry to drive the alternator of coal-fired power plants or nuclear power plants. These are steam turbine components that must withstand high steam pressure.


  • for the product presentation below, we offer low- and medium-alloy steels, or ductile iron, (e.g. GS45, GS52, G17Mn5, GE240, GP240GH, 20L, 25L, 30L, EN-GJS-500-7), high-alloy chrome and nickel steels
  • our offer also includes highly alloyed, ferritic, austenitic, duplex, martensitic materials (more than 3500 material brands)
  • Produced on electric arc furnaces (EOP), ladle furnace (LF), equipment for deep deoxidation and degassing of steels and vacuum decarburization (VD, VOD), electro-slag remelting (ESR)
  • modifications of the chemical composition requested by the customer are possible if the scope of the modification is agreed and confirmed by our steel plant or metallurgist


  • We can make models according to the design of our technology in wood, polystyrene, or in a combination of materials in maximum dimensions (10,000 x 5,000 x 4,000) mm
  • to ensure the production of castings, it is possible to accept customer models, if their condition and the technology of making castings correspond to our technological possibilities and requirements

Production of castings

  • of steel as mentioned above, or according to the customer’s specifications, usually in the weight range of 200 to 50,000 kg/casting, provided that the maximum dimensions of the product do not exceed 8,500 x 4,500 x 3,000 mm, which is limited by the size of the annealing furnaces, possibly tempering baths
  • all standard heat treatment processes are available

Quality control

  • EN ISO 9001, EB ISO 14001, OHSAS 18001
  • ISO 17025 accredited laboratory – chemical, metallographic, mechanical, non-destructive testing (MT, PT, UT, X-ray), dimensional control (3D camera)
  • Standards used as a standard: ČSN, DIN, EN and ASTM, possibly others, if there is agreement on their use
