We studied structure, strength properties and fracture mechanism of austenitic stainless steel after thermomechanical treatments of two regimes, and further low-temperature ion nitriding. Thermomechanical treatments contributed to the formation of grain-(sub) grain structure of submicron scale in the steel containing high density of defects - the grain boundaries, dislocations and (sub)grain boundaries. Ion nitriding contributed to the formation of hardened surface layer with a microhardness of 11-12 GPa. Formation of grain-(sub)grain structure of submicron scale led to the formation of a brittle surface layers - thick nitride layer and zone of internal nitriding (solid solution hardening) in steel.
