Abstract

1,262,145. Altering physical structure; making steel plates. NIPPON STEEL CORP. 3 March, 1969 [2 March, 1968], No. 11089/69. Headings B3A and B3V. [Also in Division C7] Steel containing not more than 0À1% carbon, less than 0À2% manganese and less than 0À02% sulphur, the ratio of manganese to sulphur being more than 10 : 1 is hot rolled, cold rolled and recrystallization annealed without decarburization. Cold working may be such as to effect 50 to 90% reduction.
