Abstract
1339458 Highly drawable steel sheet USS ENGS & CONSULTANTS Inc 19 April 1971 [27 Feb 1970] 22748/71 Heading C7A A slab of a steel comprising:- C 0À03-0À1% Mn 0À005 - less than 0À15% S 0À004-0À03% O less than 0À015% P 0À02% max and Si 0À06% max, the balance, apart from incidental steelmaking impurities (such as Al and Ti), being Fe is a) hot rolled at a sufficient temperature to prevent the formation of proeutectoid ferrite (e.g. with a final pass at 1700-1830F); b) cold reducing the so-produced sheet by 60-80%; and c) soaking the sheet at 1200-1350F. for 12-30 hours to give a microstructure with most of the (111) and (112) planes in the plane of the sheet. The slab may be produced by continuous casting, the original steel melt may be treated by vacuum carbon deoxidation to obtain the correct oxygen content and the final sheet product has exceptionally high drawability.
