Plants

Steel plant

Steel and superalloys that meet the highest quality standards

The versatile combination of melting and remelting processes makes it possible to produce top-quality materials that are refined in up to three downstream melting processes.

Melting

125 ton UHP arc furnace

16 ton vacuum induction melting (VIM) furnace

6 ton and 30 ton vacuum arc (VAR) furnace

Electro-slag remelting (ESR) units

Ingot dimensions (ESR)

Forge

Special forging expertise for optimized solutions

Open-die forging presses in two different sizes (120 MN and 85 MN) are available to form the workpieces.

Forgings are close-contour machined into semi-finished and finished products in our open-die forging process using state-of-the-art forging technologies.

Heat treatment

Controlled compliance with all process parameters

The combination of selected heat treatments gives forged parts the properties required to withstand extreme stresses.

Hot spin testing

Spin testing of turbine shafts at operating temperature can be performed on four hot spin testing machines of varying sizes.

All processes are controlled, monitored and logged in the operational control center.

Machining

Custom close-contour machining

An extensive range of machinery is available for close-contour and near-net-shape machining of workpieces, which ensures high production quality. The machining workshop is equipped for all machining tasks required to produce components according to customer drawings – including milling, turning, drilling, sawing and honing.

We are also happy to offer you machining of large components on a contract basis. You can find more information on this under the category “Contract manufacturing”.

Non-destructive testing (NDT)
Reliable safeguards

Our modern ultrasonic testing facilities with sophisticated non-destructive testing methods provide our customers with assurance of reliable, defect-free products with all the required properties.

We are equipped with a variety of automated ultrasonic testing systems for shaft- and disk-shaped workpieces. Ultrasonic testing in immersion systems is also possible if customer specifications call for it.

Laboratories
Excellent equipment and specialized expertise

In addition to our own quality control system, we make use of the facilities and expertise in the central testing laboratories of Saarstahl AG, our parent company. This means we have superb equipment and specialized expertise in the field of chemical, mechanical and metallographic testing at our disposal. All test results are documented. We also undergo inspections by independent testing institutions.
