Oriented Electrical Steels

Oriented electrical steels are iron-silicon alloys that were developed to

provide the low core loss and high permeability required for more

efficient and economical electrical transformers. Available in grades M2, M-3, M-4 and M-6, with superior magnetic properties in the rolling

direction, oriented steels are used in transformer cores. They are used

in large generators and other apparatus when the design permits the

directional magnetic characteristics to be used efficiently. The AK Steel

Technology Center continues to develop new and improved grades to

provide the electrical industry with core materials for the manufacture

of more efficient electrical apparatus.

TRAN-COR® H

TRAN-COR H high-permeability electrical steels offer an outstanding

degree of grain orientation. The result is far lower core loss than

possible with conventional grain-oriented electrical steels. These

"super-oriented" materials provide higher permeability, particularly at

higher operating inductions, and the potential for producing less noisy

core structures due to lower magneto-striction. Laser scribing TRANCOR H electrical steels provides additional beneficial core loss

reductions through domain refinement. A highly focused Nd:YAG laser

beam is used to rapidly scan material surfaces perpendicular to the

rolling direction. They are available in grades H-O and H-1.

Nonoriented Electrical Steels

Nonoriented electrical steels are iron-silicon alloys in which magnetic

properties are practically the same in any direction in the plane of the

material. Standard grades from M-15 to M-47 are available, with the

advantages of special DI-MAX processing that enhances the magnetic

properties. Material is available Fully Processed as well as SemiProcessed, depending on grade. DI-MAX grades have superior

permeability at high inductions, low average core loss and good gage

uniformity. In addition, cold finishing plus strip annealing produce a

smooth surface and reduce buckles and waves, resulting in excellent

flatness and a high stacking factor. Applications include large and

small motors, large and small transformers, generators, lighting

ballasts and ignition coils.

Nonoriented electrical steels are iron-silicon alloys in which magnetic

material. Standard grades from M-15 to M-47 are available, with the 

advantages of special Ol-MAX processing that enhances the magnetic 

properties. Material is available Fully Processed as well as SemiProcessed, depending on grade. Ol-MAX grades have superior 

permeability at high inductions, low average core loss and good gage 

uniformity. In addition, cold finishing plus strip annealing produce a 

smooth surface and reduce buckles and waves, resulting in excellent 

flatness and a high stacking factor. Applications include large and
