Abstract

The invention concerns a steel for lightweight construction, consisting of a multiphase structure. In the case of a duplex steel, it consists of mixed ferrite (alpha) and austenite (gamma) crystals. In the case of a triplex steel, it comprises, additioally to said two phases, martensitic (epsilon) and/or (kappa) phases. The volumetric weight of the inventive steel is low as a result of the high proportion of light alloys A1, Si Mn, Mg, Ga and Be. The inventive alloys have a volumetric weight of less than 7b/cm<SUP>3</SUP>.
