CRGO steels is available in various grades depending on the specific application. The most common grades are M3, M4, and M5. The higher grades have lower core loss and higher magnetic flux density. CRGO steels is also available in different thicknesses, widths, and lengths to match specific requirements.
The major advantages of using CRGO steels in electrical equipment are its high magnetic permeability, low core loss, and excellent magnetic properties. This type of steel is specifically designed to reduce energy losses and provide greater efficiency. It is widely used in power transformers, current transformers, instrument transformers, and other electrical devices.

Properties of CRGO Steel
It is a soft magnetic material and has the following properties:
- High magnetic permeability.
- Reduced magnetostriction.
- High resistivity.
- High stacking or laminating factor allows compact core designs.
- Low losses.
Grades of CRGO Steel
- The early grades of steel were known as M7(0.7watts /lb at 1.5T/60Hz) and M6(.6watts/lb at 1.5T/60Hz).
- Similarly, M5 M4 and M3 grades were developed in the late sixties.
- A new material called Hi-B has a remarkable degree of orientation and is 2 – 3 grade better than conventional CRGO steel products.
Application of CRGO Silicon Steel as Transformer Core
CRGO grade steel mainly finds applications as core material for power transformers and distribution transformers. This can be explained as below
- High magnetic permeability leads to low excitation currents and lower inductions.
- Low hysteresis and eddy current losses.
- Excellent lamination factor leads to better and compact designs and hence low material required.
- High knee saturation characteristics.
- Very low level of magnetostriction leads to noise reduction.
- Enhances ease of winding and improves productivity.
