Purpose: Automotive industry constantly demands high-strength steels which are characterized by the energy absorption possibilities during a collision. Such materials may, in the future, replace the currently used conventional steels. The groups of steels which meet these criteria are the austenitic steels and austenitic-ferritic steels with high manganese content (15-30%) and high aluminium content (1-6%). Design/methodology/approach: The influence of the chemical composition on the mechanical properties of steel with high carbon, manganese and aluminium concentration was analysed in this paper. Moreover, the susceptibility of those steels to hot deformation was assessed in plastometric tests. Findings: The conducted research enabled the optimisation of the chemical composition of duplex steels and manufacture of steel with favourable relation of strength to ductility. Practical implications: The obtained steel is characterised by beneficial properties which outbalance the austenitic steels type TWIP and may be applied in vehicle construction on elements connected with safety. Originality/value: The achieved results will be used to develop a technology of thermomechanical treatment of duplex steels.
