Abstract
This specification covers the detailed requirements for specified grades of flat-rolled, grain-oriented, fully processed low-carbon silicon-iron electrical steels, whose low core loss and high permeability in the direction of rolling have been achieved by appropriate metallurgical processing. These steels are primarily used in transformer cores operating at moderate to high magnetic flux densities at commercial power frequencies. These steels may be acquired in any of four conditions a.) conventional grain-oriented tested at 15 kG (1.5 T), b.) conventional grain-oriented tested at 17 kG (1.7 T), c.) high-permeability grain-oriented tested at 17 kG (1.7 T) and d.) laser-scribed high-permeability grain-oriented tested at 17 kG (1.7 T). These steels can be purchased in a number of combinations of material form and surface type or treatment. This specification explains in detail, the available forms, thicknesses and magnetic performance.
Scope
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).
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.
1.3 The electrical-steel grades described in this specification include (
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.
