27QG100 0.27mm Grain Oriented Electrical Steel is a high-performance CRGO (Cold Rolled Grain Oriented) silicon steel grade widely used in transformer cores, reactors and other static electromagnetic equipment.
Manufactured according to GB/T 2521-2022, 27QG100 combines low core loss, high magnetic induction and stable processing performance. It has become one of the most commonly used medium-high grade grain oriented electrical steels for energy-efficient distribution transformers, renewable energy projects and power grid upgrading applications.
Compared with ordinary electrical steel, 27QG100 features a controlled grain orientation structure, which improves magnetic permeability along the rolling direction and significantly reduces hysteresis loss and transformer no-load loss.

Key Features of 27QG100 Electrical Steel:
The grade designation of 27QG100 contains important information about its thickness, material type and magnetic performance.
| Grade Symbol | Meaning |
|---|---|
| 27 | Nominal thickness of 0.27 mm |
| QG | High magnetic induction grain-oriented silicon steel |
| 100 | Maximum core loss value of 1.0 W/kg under 1.7T/50Hz test condition |
Unlike non-oriented electrical steel used mainly in motors and generators, grain oriented electrical steel is designed for static magnetic applications such as transformers.
Its specially controlled crystal orientation allows magnetic flux to flow efficiently in the rolling direction, reducing energy loss during transformer operation.
