1.1 This specification covers the detailed requirements to which the specified grades of flat-rolled, grain-oriented, fully processed electrical steels shall conform. These steels are used primarily in transformer cores operating at moderate to high magnetic flux densities at commercial power frequencies (50 and 60 Hz).<\/p>\n
1.2 These grain-oriented electrical steels are low-carbon, silicon-iron alloys with a silicon content of approximately 3.2 % in which low core loss and high permeability in the direction of rolling have been achieved by appropriate metallurgical processing.<\/p>\n
1.3 The electrical-steel grades described in this specification include ( 1<\/span> ) conventional grain-oriented electrical steel tested at 15 kG (1.5 T) in accordance with Test Method A343\/A343M , ( 2<\/span> ) conventional grain-oriented electrical steel tested at 17 kG (1.7 T) in accordance with Test Method A343\/A343M , ( 3<\/span> ) high-permeability grain-oriented electrical steel tested at 17 kG (1.7 T) in accordance with Test Method A343\/A343M , and ( 4<\/span> ) laser-scribed high-permeability grain-oriented electrical steel tested at 17 kG (1.7 T) in accordance with Test Methods A804\/A804M .<\/p>\n 1.4 The values stated in customary (cgs-emu and inch-pound) units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units, which are provided for information only and are not considered standard.<\/p>\n A876-09e1 Standard Specification for Flat-Rolled, Grain-Oriented, Silicon-Iron, Electrical Steel, Fully Processed Types<\/b><\/p>\nPDF Catalog<\/h4>\n
