The new lightweight steels, which possess excellent characteristics, are now of interest to the automobile industry. These steels offer a number of attractive properties (e.g high strength, high ductility, low density). However, there are some disadvantages, such as the low modulus of elasticity or the high cutting and pressing forces which they require. The higher material costs may limit the usage of these steels in mass-production automotive applications. Nevertheless, the willingness to make use of lightweight steels has increased in recent years. The extent to which these lightweight steels will displace hot-formed sheets additionally remains to be seen. A compromise will also have to be found in this case, with not only selecting the right material, but also the right process in the right location.
