27Q100 Grain-Oriented Electrical Steel
A thin-gauge grade for transformer cores that need lower loss than 0.
View details23Q090 Grain-Oriented Electrical Steel
23Q090 is specified for large cores where eddy current loss becomes a significant part of total loss. The 0.23 mm gauge reduces that component, and the coating is chosen to suit the customer's cutting and stacking method.
Because thin material is more sensitive to handling, coils are packed for transport and supplied with mill test certificates covering core loss, induction and coating class.
