- Abstract
The mechanical properties of newly developed austenitic nitrogen corrosion-resistant Cr - Ni - Mn steels with copper additive are studied in the temperature range of hot and warm deformation. The results of the hot and warm compressive tests are used to determine the specific levels of strain resistance at different temperatures of pressure treatment, which may be used for designing processes for making hot-deformed products from the experimental steels. It is shown that warm deformation and tempering are suitable for hardening nitrogen steels with the aim to apply them as nonmagnetic corrosion-resistant heat-resistant materials. The materials for cryogenic purposes should be subjected to a high-temperature thermomechanical treatment and quenching (solid solution treatment).
