SHJISCO supplies Cold Rolled Grain Oriented (CRGO) electrical steel engineered for low core loss, high permeability, and stable performance in transformer and reactor applications. This category covers multiple CRGO grades so you can match magnetic performance, noise targets, and temperature requirements to your design.
CRGO Silicon Steel is a specialized electrical steel processed to achieve a strong crystallographic grain orientation in the rolling direction. This directional grain structure helps magnetic flux flow more efficiently, which can reduce iron loss and improve energy efficiency in magnetic cores. For transformer and reactor designers, the result is a material platform that supports lower no-load loss, reduced heat generation, and more stable long-term operation.
SHJISCO organizes CRGO solutions into five practical grade families. Use the guide below to select the best-fit material for your design priorities:
Laser-oriented Silicon Steel: A domain-refined CRGO option where laser treatment is applied to the surface to refine magnetic domains and lower iron loss. It is commonly chosen when efficiency upgrades and consistent performance are key.
HIB-oriented Silicon Steel: High magnetic induction / high permeability oriented steel designed to minimize losses and support higher flux density. Often selected for high-performance power equipment where compactness and efficiency matter.
CGO-oriented Silicon Steel: A widely used cold-rolled grain oriented steel balancing strong magnetic performance with reliable manufacturing stability—frequently used for transformer core applications.
LM-oriented Silicon Steel:“Low noise + high permeability” oriented electrical steel—an option to prioritize acoustic performance and permeability in transformer manufacturing.
HS-oriented Silicon Steel: A heat-oriented / heat-resistant notched grain oriented silicon steel category intended for demanding environments where temperature stability and long-term reliability are emphasized.
Targeting lower iron loss? Consider Laser-oriented Silicon Steel (domain refinement) or HIB-oriented Silicon Steel (high induction, low loss focus).
Balancing performance and mainstream availability? CGO-oriented Silicon Steel is a common baseline choice.
Noise-sensitive designs? LM-oriented Silicon Steel is positioned for low-noise transformer core builds.
High-temperature or demanding duty cycles? HS-oriented Silicon Steel targets temperature-resistant operation.
Lower core losses: Grain orientation helps reduce hysteresis and eddy current losses, supporting higher efficiency and cooler operation.
High magnetic induction & permeability: Certain grade families (e.g., HIB-oriented Silicon Steel) are designed to reach higher flux densities, enabling compact magnetic designs without sacrificing performance.
Low noise potential: Reduced magnetostriction and optimized microstructure can help lower vibration and acoustic noise—especially relevant when selecting LM-oriented Silicon Steel for transformer cores.
Insulation coating integrity: CRGO is typically supplied with an inorganic insulating coating to maintain interlaminar insulation, supporting stable stacking/lamination performance and reducing eddy currents between laminations.
Processing-friendly dimensional control: High dimensional accuracy, uniform thickness, and stable mechanical properties improve downstream operations such as slitting, cutting, and lamination stacking.
