Allegheny Ludlum Silectron® Conventional Grain-Oriented electrical steel is processed under carefully controlled

conditions to develop optimum magnetic characteristics in the rolling direction. Grain-oriented silicon steel

develops low core losses at high inductions when used as core material in designs with the flux path parallel to the

rolling direction. These low losses at high inductions are attained with low exciting currents because of the

excellent high induction permeability of grain-oriented silicon steel. In addition, the normal operating inductions for

grain-oriented silicon steel are sufficiently below the magnetic saturation of the material to allow a comfortable

margin of safety in most designs. Processing of grain-oriented silicon steels is carefully controlled in order to

achieve a very high stacking factor for the core material. This stacking factor often exceeds 95%0 of the theoretical

maximum. The high usable magnetic induction of grain-oriented silicon steel, along with the high stacking factor,

allow compact core designs requiring the minimum amount of material to be used in the windings surrounding the

core. This contributes to low losses, not only in the core (no load losses), but also allows for the minimum load

losses or winding losses in the transformer.
