Abstract
1422766 Heat-treating silicon steel ALLEGHENY LUDLAM INDUSTRIES Inc 6 May 1974 [7 May 1973] 19805/74 Heading C7A The steel contains in percentage by wt. and is hot-rolled, optionally annealed at # 1700F, cold-rolled in one or more stages with any intermediate anneals being at # 1700F, annealed at 1400-1700F for 15 seconds to 2 hours preferably with cooling rate equivalent to that in still air before the final cold rolling which involves a reduction of at least 80%, decarburized and finally annealed to produce a cube -on-edge texture yielding a permeability of at least 1850 G/oe at 10 oe.
