Heat treatment of the steel consisted of water quenching from 1050°C. A ferrite-austenite microstructure was obtained and the brittle ?$\sigma$?-phase was avoided. The results show that the impact energy depends on the direction of rolling. In rolling direction the share of ferrite and austenite was approximately equalV članku so opisani rezultati raziskav mikrostrukture in mehanskih lastnosti dupleks jekel po gašenju v vodi s 1050°C. Na ta način je jeklo dobilo mikrostrukturo iz ferita in austenita in brey krhke ?$\sigma$?-faze. Rezultati kažejo, da je udarna energija odvisna od smeri valjanja.
