Advanced Cold-Rolled Silicon Transformer Steel: Precision Solutions for Energy Efficiency.
Grain-Oriented Electrical Steel (GOES): The Backbone of High-Efficiency Transformers
Specially engineered for transformer cores, our Grain-Oriented Electrical Steel (GOES) optimizes magnetic flux directionality via Goss texture {110}<001> alignment. With core losses as low as 0.85 W/kg @1.7T/50Hz, it ensures 98.5% energy efficiency in power distribution systems.
Key Grades & Standards
| Standard | Grade | Thickness | Max. Core Loss (W/kg) | Min. Induction (B800) |
|---|---|---|---|---|
| JIS C 2553 | 23R090 | 0.23mm | ≤0.90 @1.7T | ≥1.88T |
| ASTM A876 | 30H083 | 0.30mm | ≤0.83 @1.5T | ≥1.82T |
| EN 10107 | M130-30S | 0.30mm | ≤1.30 @1.5T | ≥1.78T |
Critical Features:
- Laser Scribing: Reduces hysteresis loss by 18%
- MgO Coating: 3–5 μm insulation layer (≥25 Ω·cm² resistance)
- Dimensional Precision: ±0.02mm thickness tolerance
Non-Oriented Electrical Steel (NOES): Optimal Performance for Motors & Generators
Designed for rotating machinery, our Non-Oriented Electrical Steel delivers isotropic magnetic properties with silicon content 2.5–3.2%. Grades like 65A310 achieve core losses ≤3.10 W/kg @1.5T/50Hz, ideal for EV motors and industrial compressors.
