Abstract

1389078 Heat treating steel sheet NIPPON KOKAN KK 24 March 1972 [27 March 1971] 14061/72 HeadingC7A Sheet suitable for drawing is obtained in a continuous annealing process from steel containing 0À02-0À1% C by heating the hot and cold rolled material to a temperature in the range (recrystallization temperature - 850‹C), slowly cooling into the range (600‹C - A), and then cooling to ambient temperature at 200‹ to 10000‹C/sec., followed by reheating to 300‹-530‹C. The steel may be held at that temperature for at least 10 seconds, or cooled to not less than 300‹C over at least 10 seconds and is then cooled to ambient temperature and temper rolled. Preferably after hot rolling the steel is cooled at not less than 630‹C In a particular embodiment the steel is initially heated to 800‹C, cooled at 5‹C/sec to 650‹C, cooled at 600‹C/sec, reheated to 530‹C, cooled at 12‹C/sec. to 300 C, and air-cooled.
