The material for driverless e-cars One in every four German-produced cars uses steel from GMH Gruppe. And steel will continue to be important in the automotive industry of the future: as an especially light and high-strength material in lightweight engineering, in e-cars and in driverless vehicles, for instance.

Climate-protection by the tonne - thanks to maximised energy-efficiency Steel is 100% recyclable. But that's not all. Efficient utilisation of the waste heat yielded in the production and processing of steel saves many tonnes of emissions every year in the GMH group's plants. Here two examples from the Georgsmarienhütte GmbH steel mill and the Gröditz forging plants.

Innovative waste-gas routing boosts plant efficiency The electric arc furnace (EAF) is the central element in steelmaking at Georgsmarienhütte GmbH - in exactly the way that improvements to processes and technologies are a central topic within the GMH group. When these two meet, the results are things, such as an innovative waste-gas routing, that improve even further tried-and-tested facilities such as our furnace.

We at GMG Gruppe provide our customers with perfect solutions in iron and steel casting – from the patterns all the way down to shipment of the castings - for their entire value chains. With our know-how and expertise concentrated at two locations in Germany, we meet even the most complex and specific customer requirements.

Connecting rods: 10% lighter thanks to new material 28 grams make a world of difference in automotive engineering. Using the GMH group's innovative 46MnVS5 material, they can be saved on crack connecting rods. This makes this new grade of steel the reliable solution in lightweighting – and the ideal candidate for parts such as connecting rods in the higher performance categories.

New materials for the automotive industry The introduction of the EEG (German Renewable Energy Sources Act) surcharge has significantly increased the pressure for the industry to become more energy-efficient. Working closely with our customers in the automotive industry, we have developed two new steels that will play a significant role in saving energy. In turn, these have provided a platform on which we have been able to come up with new concepts for energy-efficient, cost-effective process...

Cut lengths (also known as short pieces) are needed whenever high-quality steel bar or bright steel is to be sawn precisely to the customer's dimensional specification. GMH Gruppe is the top address in this field, assuring ultra-tight tolerances and a broad range of grades.

Our experts have been producing and continuously further developing rotor retaining rings for more than a century - a store of experience that has made us the leader on the world market. By withstanding the enormous forces that occur in power generation, our rotor retaining rings serve as the guarantors of safety in turbo-generators.

Advantages over conventional methods 3D-printed products and components have long been much more than just another new trend in manufacturing. Annual market growth of a constant approx. 15%, depending on the particular sector, demonstrates that 3D printing is, instead, a now widely used, groundbreaking production process.

Steering racks using the warm forging process GMH Gruppe produces high-quality steering racks for leading automotive-industry manufacturers, including VW, TESLA, BOSCH, JTEKT, NEXTEER, INA, MANDO, MOBIS, ZF/TRW. These steering racks are noted for maximum precision and maximum dimensional accuracy.
