In automotive design, higher safety requirements, lower weight and CO2 emissions, and compact design, all speak for the use of ultra high strength steels. But still today there is a lot of caution when such steels are used, due to presumed lack of formability. In the current paper, a design is shown which clearly shows the potential when using such steels, but also the formability and ability to withstand deformations in a crash situation. The application is an inflateable side impact beam for a passenger vehicle. The inflateable side impact beam is a compact module made of thin walled metal and pyrotechnics comparable to the ones used for airbag application. The material used for the structure is Docol 1200 M, an ultra high strength cold rolled martensitic steel
