It has high magnetic induction (Bs), but relatively higher iron loss and lower permeability. ‌Oriented steel‌: Grains are highly aligned along the rolling direction, exhibiting strong directionality. It has high permeability and extremely low iron loss in the rolling direction, but significantly reduced magnetic performance in the transverse direction.   Chemical Composition‌ ‌Non-oriented steel‌: Lower silicon content (typically 0.5%–3.0%). ‌Oriented steel‌: Higher silicon content (≥3.0%), with the addition of carbon (0.03%–0.05%) and inhibitors to control grain orientation.   Production Process‌ ‌Non-oriented steel‌: Relatively simple process involving hot rolling, cold rolling, and annealing, resulting in lower production costs. ‌Oriented steel‌: Requires complex processes (e.g., high-temperature annealing, inhibitor treatment) to form grain orientation, making production more difficult and costly.   Application Scenarios‌ ‌Non-oriented steel‌: Primarily used in rotating electrical machinery (e.g., generators, motors) cores, where isotropic materials are needed due to varying magnetic field directions. ‌Oriented steel‌: Used in transformer cores, where fixed magnetic field directions require low loss and high permeability along the rolling direction.   Performance Comparison‌   Property Non-oriented Steel Oriented Steel   Iron Loss Higher Extremely low (approx. half that of non-oriented steel)   Permeability Lower High (permeability in rolling direction is 2.5 times higher)   Magnetic Anisotropy None Significant (optimal performance in rolling direction)   Summary‌: Non-oriented steel is suitable for applications requiring multi-directional magnetization, such as motors, while oriented steel is specifically designed for fixed magnetic field devices like transformers, emphasizing low loss and high permeability. Selection should be based on specific application requirements.
