  • Cold rolled, ductile, high strength steel strip and sheet and method therefor
    Patent number: 4067754
    Abstract: Cold reduced, annealed steel strip and sheet stock having 0.2% yield strength of 45 to 65 ksi with an elongation of at least 25%, or having a yield strength of at least 90 ksi with an elongation of at least 10%. A low carbon steel (0.02-0.10% C) typical of rimmed or drawing steel analysis is preferably vacuum degassed, and 0.02% to 0.18% columbium is added. The casting is hot rolled, coiled not higher than 1300.degree. F, cold reduced 40% to 70%, and annealed at low temperature for a time sufficient to restore desired ductility without substantially decreasing yield strength.
    Type: Grant
    Filed: April 8, 1976
    Date of Patent: January 10, 1978
    Assignee: Armco Steel Corporation
    Inventors: James A. Elias, deceased, John R. Newby, Marvin B. Pierson
