Economical Stainless Nitrogen Steels: Promising Substitutes of Light Alloys

Main process and mechanical properties of corrosion-resistant steels with a structure of nitrogen martensite are considered. Advantages of such steels over light (aluminum, titanium) alloys with respect to specific static and cyclic strength, process ductility in hot and cold state, and fracture toughness are determined. It is possible to organize wide-scale production of semiproducts and articles from such steels at Russian plants of quality metal products. __________ Translated from Metallovedenie i Termicheskaya Obrabotka Metallov, No. 7, pp. 9 – 13, July, 2005.
