Oriented Silicon Steel B27G120

Oriented silicon steel B27G120 is another grade of oriented silicon steel that is used in electrical applications. Similar to the previous example, the "B" in the designation indicates that it is a fully processed, grain-oriented electrical steel. The "27" represents the thickness of the material in mils (1 mil = 0.001 inch), and the "G" signifies the grain orientation of the steel. The number "120" in the designation refers to the nominal core loss of the steel at a specific induction and frequency. Core loss is a measure of the energy dissipated in the core of an electrical device, and lower core losses are desirable for improved efficiency.
