High Magnetic Induction Grain-Oriented Silicon Steel 23Q085
Product Summary: 23Q085 is a high magnetic induction grain-oriented silicon steel (Hi-B) specifically designed for the cores of HVDC converter transformers and high-efficiency power transformers. With a thickness of 0.23 mm, it offers excellent magnetic properties: iron loss (P₁.₇/₅₀) ≤ 0.85 W/kg and magnetic flux density (B₈) ≥ 1.88 T. Manufactured with strict control of impurities, this material ensures reliable performance in demanding energy transmission applications.
Key Selling Points
Ultra-Low Iron Loss (≤0.85 W/kg): Reduces no-load and load losses in transformer cores, significantly improving energy efficiency and lowering operational costs.
High Magnetic Flux Density (≥1.88 T): Enables transformer cores to achieve higher magnetic induction, allowing for more compact and efficient designs.
High Magnetic Induction (Hi-B) Grade: Special processing maximizes grain orientation, providing superior performance for high-demand applications.
Thin 0.23 mm Thickness: Reduces eddy current losses, further enhancing efficiency in high-frequency operations.
Strict Quality Control: Impurities such as C, S, N are tightly controlled, ensuring consistent material properties and reliability.

Materials and Structure
The material is primarily iron (Fe) with silicon (Si) added at about 3.0% - 3.2%. It also contains aluminum (Al) and manganese (Mn) as alloying elements. The manufacturing process ensures strict control of impurities such as carbon (C), sulfur (S), and nitrogen (N). This Hi-B steel features a Goss texture, which provides excellent magnetic permeability in the rolling direction, essential for transformer core applications.
Applications
Primary applications include:
High-voltage direct current (HVDC) converter transformers
High-efficiency power transformer cores
Customization
HL AND SL LIMITED offers in-house processing capabilities to meet specific customer requirements for size, shape, and performance. Cutting, slitting, and other value-added services are available to ensure the material is "customized on demand and ready to use."
Case Study
In the Brazilian ±800kV UHVDC project Belém Mountain Phase II, this material was used for converter transformers. The project required ultra-low loss, high magnetic flux density (≥1.92T), and iron loss lower than 0.85W/kg, all of which were met by this product. The transformers have been operating continuously at ±800kV/4000MW, demonstrating the material's reliability in harsh tropical conditions.
