Popis:	1. It is established that the level of carbide and nitride phase dissolution in chromium-manganese steels of type Kh16G18 with a varible ratio of carbon and nitrogen in them reaches a maximum at 1150°C. With an almost identical lattice spacing the degree of its distortion in steel with nitrogen is greater and therefore the specific electrical resistivity of the steel is higher. 2. The degree of strain hardening for austenitic steel type Kh16G18 containing carbon and nitrogen depends on the relationship between these elements, and as a rule it is greater, the higher the nitrogen content, which is connected with the higher structural defect density and formation of e-martensite in steel with nitrogen. 3. In chromium-manganese steel type Kh16G18 with the maximum nitrogen content (0.45%) after cold plastic deformation with etru = 1.2 a higher level of strengthening was achieved with retention of its nonmagnetic nature than for steel with 0.45% C.
