The automotive industry is a constantly changing market regarding design and choice of materials. The steel has since the early 1900s been the single largest component of a car, both in percentage and weight. Consumers are now demanding more fuel-efficient cars inter alia to reduce global energy consumption. This leads car manufactures to make lighter, but still safer cars. This study mainly focuses on the factors that will influence the steel usage in the automotive industry. The study will also answer what effect the future steel intensity in the automotive industry will have on LKAB’s customer portfolio. The study showed that customers of LKAB would have to spend a substantial capital in R&D to ensure the future development of new types of steel and to be able to continue their relationship with car producers. The study also showed that the future steel intensity in passenger cars would decrease with an increasing usage of high strength steels as well as an increased usage of different materials to ensure customers future demands.
