Aging processes, stability of the structure and strengthening of the nitrogen-containing stainless Cr-Ni steels were investigated using X-ray structure analyses, light and electron microscopy, mechanical testing and determining of a corrosion resistance. The aus-maraging ausaging steels with increased nitrogen content (0.12-0.20%) and methods of their thermomechanical treatment were elaborated. For nitrogen-containing austenitic and austenitic-martensitic steels, it is possible to achieve, due to stress-induced martensitic transformation and thermomechanical treatment optimization, high strength level of martensitic-austenitic steels in a combination with high plasticity and fracture toughness inherent in pure austenitic structures.
