ArcelorMittal Europe – Flat Products
ArcelorMittal and its partners continue to drive innovation in automotive manufacturing. The Steel E-Motive programme, an ambitious initiative by WorldAutoSteel, aims to revolutionise future mobility through autonomy and sustainability thanks to smart steel and ArcelorMittal Multi Part Integration® solutions.
WorldAutoSteel’s Steel E-Motive programme was managed in partnership with Ricardo.

One of the significant achievements of the Steel E-Motive programme is its utilisation of Advanced High Strength Steel (AHSS) innovations.
Seven new AHSS applications have been developed to deliver a safe, efficient, and affordable structure.
The Steel E-Motive programme incorporates various advanced features that ensure high levels of occupant comfort and accessibility, competitive weight, cost-effective design, and suitability for global high-volume production. This exceptional performance has
been achieved through innovative designs and the use of a high proportion of Press Hardening Steels (PHS) (33%) and MartINsite® grades (16%).
Without a driver cockpit, the large interior space allows passengers to face each other, improving the sense of roominess and ride comfort. This innovative design has pushed the safety structure to the vehicle’s edge, resulting in a short front structure while still meeting high-speed crash safety requirements.
Steel E-Motive’s B-pillarless one-box open body structure provides a wider door aperture for easy access and cargo use.
The lateral structure features a large laser-welded blank Press Hardened Steel Door Ring, known as an ArcelorMittal Multi Part Integration® (MPI) solution.
The Door Ring is tailored in grades and thicknesses to put the right material in the right place. Strong 2000 MPa material is used on the A-pillar, such as ArcelorMittal’s Usibor®2000, to withstand frontal loads.
Ductile material like Ductibor®1000 is used on the middle section to absorb energy in lateral pole crashes and to protect the battery.
1500 MPa material, such as Usibor®1500, is used on the C-pillar to ensure good passenger protection in lateral crashes.
Through these concerted efforts, ArcelorMittal and its partners are not only addressing current challenges but also paving the way for future innovations in the automotive sector. The Steel E-Motive programme is a testament to what can be achieved when industry leaders come together with a common goal of creating a smarter, safer, and more sustainable world.
