RUSTPROOF NANOSTRUCTURED FERRITE STEEL Russian patent published in 2012 - IPC C22C38/34 C22C38/22 B82B1/00

Abstract RU 2452788 C2

FIELD: metallurgy.

SUBSTANCE: steel contains the following components in wt %: carbon - less than 0.03, manganese - 0.20-0.80, chromium - 12.0-14.0, silicon -0.5-3.0, molybdenum - 1.0-2.0, sulfur - not over 0.005, phosphorus - not over 0.001, iron and unavoidable impurities making the rest. After bulk nanostructuring, complex secondary phases are formed on dislocation walls of ferrite matrix lattice substructure with nanoparticle sizes not exceeding 10 nm.

EFFECT: higher resistance against common and pitting corrosion, lower costs.
