voestalpine is currently focusing on the research and development of high-strength steels for lightweight automobile construction.

Leichtbau mit High Ductility StählenThe higher strength of these steels reduces the amount of material required and therefore the overall weight, which is why these steels are mainly used in lightweight automotive construction. To meet this demand, intensive work is now being done on multiphase steels for the next generations of car bodies. A special product in this segment is high ductility steel. These steels are stronger, yet malleable. In the future, top automotive manufactures will use these steels for side members, A and B pillars, doors and door sills.

High-strength steel will replace conventional steels in many areas in the future. Even now, many manufacturers of hybrid and electric vehicles are requesting higher strength electrical steel strips with excellent magnetic properties. The centrifugal forces caused by these extremely high speed motors can cause the rotor to fail, destroying the motor. voestalpine is working on minimizing failures in electric motors and reducing the electromagnetic losses of the electrical steel strip package. Both of these together increases the efficiency of electric motors and also makes them more suitable for everyday use.

Using these new steel makes motors more efficient and cars lighter, which means that smaller batteries can be installed. And cars made with these new steels can travel longer distances on a battery with equivalent size and performance. This is an exciting market for voestalpine with a lot of growth potential.
