Anotace textu normy ASTM A876-17(2026) :

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.
