Grain Oriented Electrical Steel plays a crucial role in the production of motors and transformers that are in high demand. It is manufactured in various forms to ensure high conductivity and minimal iron losses, meeting the stringent quality standards set by reputable steel mills, such as those outlined by ASTM/NSC.

Guangzhou/ ShenzhenWhat is the main difference between oriented and non oriented silicon steel?
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.
