Steel Division



Castings for energy applications (< 10 tons)

We are a renowned supplier to the energy sector and comply with applicable international norms. The used materials are creep-resistant and cryogenic special steels with special properties. Castings in nickel-based alloys complete the portfolio. Finish-machined parts and component manufacturing allow supply of ready-to-install castings.

The maximum weight of castings for the energy industry is roughly 10 tons. Because the parts find their applications worldwide, they are manufactured and certified in compliance with both EN and ASTM norms and standards.

Steam turbines

Our components for steam turbines have been certified by all renowned steam turbine manufacturers. Some examples of these innovative products are as follows: valves, interior housings, admission ports, seal housings, elbows, covers, vane supports

Gas-driven turbines

Our ready-to-install special parts for gas-driven turbines with customer-determined specifications are in high demand. Examples of special parts: vane supports, diffusors, bearing and exterior housings, seal rings

Water turbines

Based on our many years of experience and our high-quality metallurgical equipment, we are a reliable partner for all renowned turbine manufacturers. We manufacture castings for Francis, Kaplan and Pelton water turbines, including hubs, collars, Pelton wheel buckets, guide blades and adjusting cranks

Oil and gas

voestalpine Giesserei Traisen GmbH is specialized in the application of cryogenic materials. We have been supplying the international oil-field equipment industry for decades with ready-to-install and pre-assembled components. Examples of these products are as follows: compressor housings, compressors, blowout preventers, valves, bearing housings, expander housings.

Nickel-based materials

voestalpine Giesserei Traisen GmbH was heavily involved in the development of this product group for foundries. Nickel-based materials are characterized by high load-carrying capacity at high temperatures and pressures. Areas of application include, for example, steam-driven power plants that operate at 700 °C. Valves and admission ports are examples of successful nickel-based products.


Steel castings for the energy industry (> 10 tons)

Together with our customers, we achieve highest-quality products for applications in the energy industry: Our complex designs, high-alloy cast parts up to 200 tons in weight and the development of new materials are only a few of the many examples.

Fields of application

We deliver our steel castings worldwide to all renowned plant builders in the energy sector. The most essential fields of application are as follows:

  • Power generation: Gas, steam and industrial turbines
  • Oil and gas industry: Compressors, valves, etc.
  • Offshore industry: FPSOs, oil platforms, etc.

Broad range of products and services

All of the industry-specific materials are found in our product range. We are also in a position to develop new and complex alloys for special customer requirements and extreme applications, for example in nickel-based alloys for the achievement of higher degrees of efficiency. All of the castings are available in pre-ground or in finish-machined condition. Ready-to-install parts save our customers time and money. Deposit welding and pressure testing round off our portfolio.
