    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.

    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 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.

    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.
