FIELD: metallurgy.
SUBSTANCE: invention has attribute to steel, used in machinery construction for products, which are made a demand for providing high strength and corrosion-resistance with satisfactory plasticity. High-strength corrosion-resisting ferrite steel, contains carbon, chromium, nickel, cobalt, molybdenum, titanium, aluminium, zirconium, hafnium and iron, with the following ratio, mass %: contains carbon up to 0.03, chromium 8.0-25.0, nickel 5.0-18.0, cobalt 1.5-10.0, molybdenum 0.8-6.0, titanium 0.5-1.02, aluminium 6.1-9.0, zirconium + hafnium up to 0.1 and iron - the rest.
EFFECT: steel has the heightened level of strength and corrosion qualities.
