The main distinction lies in the internal structure between oriented and non-oriented silicon steel sheets. In oriented silicon steel, the grains are predominantly aligned in a single direction, hence the term "oriented." On the other hand, non-oriented silicon steel exhibits a random grain arrangement, resulting in higher heat loss compared to its oriented counterpart. This characteristic makes grain-oriented silicon steel suitable for meeting the stringent processing requirements of transformers and rotors.

Cold Rolled Grain Oriebted Electrical Steel Advantages
Grain-oriented electrical steel usually has a silicon level of 3% (Si:11Fe). It is processed in such a way that the optimal properties are developed in the rolling direction, due to a tight control (proposed by Norman P. Goss) of the crystal orientation relative to the sheet. The magnetic flux density is increased by 30% in the coil rolling direction, although its magnetic saturation is decreased by 5%. It is used for the cores of power and distribution transformers, cold-rolled grain-oriented steel is often abbreviated to CRGO.
CRGO is usually supplied by the producing mills in coil form and has to be cut into "laminations", which are then used to form a transformer core, which is an integral part of any transformer. Grain-oriented steel is used in large power and distribution transformers and in certain audio output transformers.
CRNGO is less expensive than CRGO. It is used when cost is more important than efficiency and for applications where the direction of magnetic flux is not constant, as in electric motors and generators with moving parts. It can be used when there is insufficient space to orient components to take advantage of the directional properties of grain-oriented electrical steel.
