    Lightweight Forging Initiative

    1,917 ideas and 358 kg of potential Making heavy things lighter is something that drives us onward every day. This is especially true of high-strength steels for the automotive industry. Working together with numerous project partners, we have discovered, in the "Lightweight Forging Initiative", enormous potential for weight reduction – an important stride into the future. Reducing the weight of vehicles is one of the most significant challenges for future mobility. If forged parts and other...

    Utilisation of waste heat in the steel industry

    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. The steel industry is one of Germany’s most energy-intensive industries. Energy is necessarily used in industrial processes such...

    The electric arc furnace: New directions

    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. The melting of scrap in an electric arc furnace to make steel inevitably results...

    Top-performance lightweighting

    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. The car of the future will run using steel of the future: high and ultra-high strength, to meet the growing demands...

    High-strength steels with high energy efficiency

    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...

    3D printing: The future models for us

    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. By July 2019, one in every three industrial companies had analysed the potentials of 3D printing. The many benefits of this technology have enabled the major component...

    World-beating innovations in steering technology

    High-tech steering racks set new precision standards Since 2012, GMH Gruppe company Metallverarbeitung Ostalb has been using the patented warm-forging process to produce top-grade components for automotive steering systems. A second, technologically even further refined warm-forging cell now permits new capacities, materials properties and high-precision fine adjustments. Automotive steering systems are safety-critical and thus demand maximum precision and dimensional accuracy....

    Lightweighting: The powertrain for the future

    Hybrid vehicles that save weight and CO2 Lightweighting using steel makes vehicles future-viable: they not only reduce weight and fuel consumption, they also save the environment a whole lot of harmful emissions. This is also shown by the results of the "Lightweight Forging Initiative", in which Georgsmarienhütte GmbH played its part. Light, but nonetheless ultra-safe, ultra-strong and ultra-durable – the powertrain for the car of the future will not be possible without high-strength steel - and...

    Bainitic steel: potential for 30 % savings

    Optimum properties, rational production costs Bainitic steels combine the optimum properties of quenched and tempered (QT) steels with the short production routes of PHFP steels. This fact makes steels like Georgsmarienhütte GmbH's 16MnCrV7-7 (H2), 1.8195 the ideal steel for structural components in automotive engineering: assured versatility at rational cost. The automotive industry makes demands that are well above average on its steel. Here, microalloyed air-hardening bainitic steels such as...
