Excellent quality, flexible applications

Products & services

With over five hundred different grades, GMH steel has a key position within the industry. Georgsmarienhütte GmbH manufactures a wide variety of premium-quality steel products – from crude steel and bar steel right through to bright steel.

Production plants

Cast ingot

Product

Our customers’ requirements are constantly changing. But with crude steel, we have an answer to these market dynamics that is both reliable and impressive.

The crude steel is produced in an electric arc furnace (EAF). With a batch weight of around 140 tonnes, the liquid steel is cast into ingots subject to a successful secondary metallurgy process.

Size range:
  • Weight: 3.5–44-tonne ingots for open-die forging
  • Shape: 4-edge, 8-edge and 16-edge

Continuous casting

Product

As an alternative to the ingot, we also offer you the billet form. 

Following crude steel production process in the electric arc furnace, the steel enters the 6-core continuous casting line and is poured into blooms. 

Contact our Bous site for information concerning further block formats. 

Range:
  • Dimensions: 165 x 165 mm and 245 x 245 mm 4-edge
  • Delivery lengths: 3.5 to 7 m

Steel bar

Product

Georgsmarienhütte GmbH produces steel bars in compliance with the highest standards of the automotive supplier, mechanical engineering and capital goods industries.

In the rolling mill precision roller units produce steel bars with extremely precise tolerance according to the Kocks system. The material is produced with individually-required material properties - according to customer needs - with optional heat treatment.

Bright steel

Product

The diversity of our customers’ end products is huge, which is why the range of materials we manufacture has to follow suit. 

By using our own peeling machines, we are able to achieve the perfect surface structure and roundness. This also means we can manufacture premium-quality bright steel with excellent properties from rolled bar steel.

Application development

Service

We work closely and intensively with our customers to develop new and advanced steel materials to fulfil the diverse requirements of various markets. Optimising the technological and resource efficiency of your components is always a priority. A variety of simulation programmes are used in an early stage of the development work.

Advantages:
  • Consideration of the entire process chain
  • Use of lightweight construction possibilities
  • Fewer resources used in component manufacture
  • Improvement in overall efficiency of your end products

Simulation

Service

Simulation programmes are used in an early stage of the development work.

Strength and ductility are tailored to the load profiles of the later component to increase the service life of components and to develop damage-tolerant component properties.

Benefits:
  • Optimising individual processes of the production chain
  • Quickly and effectively using lightweight construction potentials
  • Improving the overall efficiency level of end products
