CRGO (Cold Rolled Grain Oriented Steel)
CRGO Steel is a high-performance material used in transformer cores due to its superior magnetic properties and low core loss. It is widely used in power transformers to ensure optimal efficiency and minimal energy wastage.
Technical Details of CRGO
CRGO or Cold Rolled Grain Oriented Steel is available in various grades (generally called M3, M4, M5 & M6). Major international standards such as Japanese (JIS), American (ASTM), German (DIN), and British Standards specify CRGO grades.
Grades of CRGO Steel
The early grades of steel were known as M7 (0.7 watts/lb at 1.5T/60Hz) and M6 (0.6 watts/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 grades better than conventional CRGO steel products.
