HIGH-STRENGTH CORROSION RESISTANT STEEL Russian patent published in 2001 - IPC

Abstract RU 2175684 C2

FIELD: metallurgy, more particularly high-strength corrosion-resistant steel for cryogenic temperatures used in aircraft, cosmic industries and in other fields of engineering. SUBSTANCE: described is high-strength corrosion- resistant martensitic class steel comprising wt %: carbon, not higher than 0.03; chromium, 10.0-13.0; nickel, 8.0- 11.0; titanium, 0.02- 0.15; molybdenum, 0.4-0.9; cobalt, 0.2-0.6; boron, 0.001-0.005; calcium, 0.001-0.05; lanthanum, 0.01-0.1; and iron, the balance. Method makes it possible to increase reliability of use of steel in complex soldered-welded structures. EFFECT: greater impact strength of base metal in zone of heat affected weld.
