High magnetic induction & low core loss electrical steel designed for high-efficiency transformers, reactors, and energy systems.
Oriented Electrical Steel, also known as Grain-Oriented Electrical Steel or Cold Rolled Grain-Oriented Silicon Steel (CRGO), is a high-performance electrical steel specifically engineered for high-efficiency power transformers, reactors, and energy systems. Its precisely controlled grain orientation significantly reduces magnetic core loss and improves permeability, enabling stable and energy-efficient performance.
This material is widely recognized in the industry under various names including Grain-Oriented Silicon Steel, High Magnetic Induction Grain-Oriented Steel, and Low Core Loss Electrical Steel. Internationally, it is commonly abbreviated as GO or CRGO.
Oriented Electrical Steel is an essential material for energy-critical electrical equipment. Typical application scenarios include:
| Application Area | Typical Usage |
|---|---|
| Power Transformers | Core laminations for utility and distribution transformers |
| Reactors & Inductors | High-efficiency magnetic cores |
| Power Grid Systems | Transmission and distribution equipment |
| Renewable Energy | Wind, solar, and energy storage transformer systems |
| Industrial Electrical Equipment | High-efficiency electrical machinery and power devices |
| Thickness (mm) | Nominal Width (mm) | Inner Diameter (mm) |
|---|---|---|
| 0.23 / 0.27 / 0.30 / 0.35 | 700 – 1200 | 508 |
| Item | Tolerance |
|---|---|
| Thickness Tolerance | ±0.02 mm |
| Longitudinal Thickness Difference | ≤ 0.03 mm |
| Transverse Thickness Difference | ≤ 0.02 mm |
| Width Tolerance | 0 ~ +2 mm |

We supply Oriented Electrical Steel compatible with major global steel standards, including Baosteel, WISCO, NSC, JFE, Cogent, TKS, POSCO, AK Steel, and others. Full grade equivalence lists are available upon request.
All Oriented Electrical Steel products comply with IEC and ASTM standards and are delivered with Material Test Certificates (MTCs). Custom slitting, lamination, and packaging services are available.
Oriented Electrical Steel, also known as CRGO (Cold Rolled Grain-Oriented Electrical Steel), is a silicon steel with a highly controlled grain structure. The grain orientation is optimized to achieve low core loss and high magnetic permeability, making it ideal for transformer and reactor cores.
CRGO steel has a directional grain structure designed specifically for magnetic flux flow in one direction, which significantly reduces energy loss. Non-oriented electrical steel (NO) has random grain orientation and is typically used in rotating machines such as motors and generators. CRGO is mainly used for transformers, while NO steel is used for motors.
Standard thicknesses include 0.23 mm, 0.27 mm, 0.30 mm, and 0.35 mm. Other thicknesses may be available upon request depending on grade and quantity.
