With abundant experience, we warmly welcome you to wholesale customized astm standard grain oriented silicon steel coil from our factory. For price consultation, contact us.
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.
