The International Steel Sheet Summit will once again take place at the TEMA Pyramid in Aachen, Germany, 24-25 April 2024.
The first edition of IESSS took place in 2022, since then new technology and progress has been made with Electromobility, where electrical steel sheets are the central product. Highly powerful electric drives must now be further developed. Moreover, high electricity costs and climate change are having an even greater impact on the global community and yet, further reduction of CO2 emissions is essential.

ESSS will bring all partners of this specific value chain together, to exchange experiences and to improve the power and efficiency of e-drives. This is an elementary condition to increase customers’ acceptance and awareness of this technology.
IESSS fosters collaboration among stakeholders for research exchange, aiming to enhance electric vehicle performance and increase customer acceptance through standardization.

Topics and sessions

Steel grades: compositions, microstructures, textures, mechanic and magnetic properties, dimensions, applications, customized grades for special motor designs such as EV (including design studies).
Production of es-sheets: melting, casting, cold rolling, annealing, coating, process-integrated testing methods, new process routes such as Twin-rolling, Belt-casting, additive manufacturing.
Processing technologies: cutting technologies such as stamping, laser cutting, join-ing technologies for stack production such as welding, interlocking, bonding, bond-ing varnishes like Backlack.
Modelling, simulation and testing: material properties, components, joints, process-es, innovative testing methods, characteristic values, drive cycle consideration for e-mobility, quality assessment and parts integrity.
Standardization: international standards for material and testing (ISO, IEC, EN), technical rules such as VDA (automotive) and others.
Other focuses: In addition to Electromobility, further processes to be discussed will focus on cutting, joining, production of electric drives, as well as their design and adaption in vehicles. Greater testing, scientific research, modelling and simulation of microstructure properties and the behavior of components in real operation is critical for further development.
