Grain oriented electrical steels were developed to provide the low core loss with higher efficiency for electrical transformers. Grain oriented electrical steels with very high proportion of grains within the steel with superior magnetic properties in the rolling direction. They provide superior permeability and lower core loss when magnetized. M – Grades, (M-2, M-3, M-4, M-5 and M-6) Grain Oriented Electrical Steels are conventional grades produced by AK Steel are used most effectively in transformer cores having wound or sheared and stamped laminations. They also are used in large generators and other electrical equipments for power generation and distribution purposes.

TRAN-COR H High-Permeability Electrical Steels produced by AK Steel offer an outstanding degree of grain orientation. The result is far lower core loss than possible with conventional grain-oriented electrical steels. In addition, these “super-oriented” materials produced with Laser Scribing Refines Domains provides additional beneficial core loss reductions through domain refinement and Superior Lamination Factor.

These materials are most appropriate for stacked-core.

Grain Oriented Electrical Steels from AK Steels are supplied with Glass-type, Lite-carlite and Carlite 3 Insulations. Glass-type and Lite-carlite type insulations are adequate for wound cores and toridol cores type used in distribution transformers.

CARLITE 3 Insulation, applied to any of the oriented and TRAN-COR H grades, this coating are adequate for stacked cores for power and distribution type transformers.

D - Coating and T - Coating are specialty of Allegheny Ludlum Steel.

D – Coating is similar to Glass-type and Lite-carlite type insulations and T – Coating is adequate for stacked cores.
