Beschreibung
Zusammenfassung:	FIELD: metallurgy; production of high-strength corrosion-resistant austenitic steel. ^ SUBSTANCE: the invention is pertaining to the field of metallurgy, in particular, to a production of high-strength corrosion-resistant austenitic steel used for production of elastic elements. The corrosion-resistant austenitic steel contains components in the following ratio (in mass %): carbon - up to 0.03; chromium - up to 8-25; nickel - up to 5-18; cobalt - up to 1.5 - 10; molybdenum - up to 0.8 - 6.0; titanium - up to 0.5 - 1.02; aluminum - up to 0.4 - 6.02; lanthanum or calcium - up to 0.005 - 0.15; iron - the rest. The technical effect of the invention is an increase of the tensile strength of the high-strength corrosion-resistant austenitic steel up to 2600 MPa. ^ EFFECT: the invention ensures an increase of the tensile strength of the high-strength corrosion-resistant austenitic steel up to 2600 Mpa. ^ 1 ex
