23Q090
23Q090 Grain-Oriented Electrical Steel
The thinnest grade in the range, for large power transformer cores where eddy current loss dominates the loss budget.
View details23R075 Grain-Oriented Electrical Steel
23R075 combines a 0.23 mm gauge with high permeability, which lowers both eddy current loss and excitation current in transformer cores. It is chosen where no-load loss and core size are tightly constrained.
Material is supplied slit to the core width required by the winding line, with edge quality controlled to protect the insulation coating. Mill test certificates covering core loss, induction and coating class are issued with each delivery.
