Abstract

1,051,307. Altering molecular structures; working at specified temperatures. RICHARD THOMAS & BALDWINS Ltd. Aug. 19, 1965 [Aug. 19, 1964], No. 33897/64. Heading B3V. A method of counteracting the appearance of stretcher-strain markings on rimming steel comprises subjecting the steel in the annealed state to slight plastic deformation at a temperature at least as low as - 78‹ C. Up to 5% plastic deformation may be effected by rolling at temperatures ranging to -196‹ C., the temperature of liquid nitrogen.
