Abstract

1342120 Steel for galvanising NIPPON KOKAN K K 19 April 1971 [4 Feb 1970 (4)] 21946/71 Heading C7A Steel containing 0À03 to 0À06%C and 0À05 to 0.1% of oxygen is slabbed, hot rolled, pickled, decarburisation annealed at not more than 800‹C before and/or after cold rolling, or between two cold rolling stages, to reduce the carbon content to less than 0À01%, reannealized between the recrystallisation temperature and A 3 , cooled, hot dip galvanised and temper rolled.
