AK STEEL TRAN-COR" H 

GRAIN ORIENTED ELECTRICAL STEELS PRODUCT DESCRIPTION --

SPECIFICATIONS 

In terms of maximum core loss, TRAN-COR H specifications are determined at l.7T at either 50Hz or 60Hz. Core loss grading is conducted 

using as-sheared sing le sheet test samples which are tested in accordance with ASTM test method A 804. Indudion is specified at 800 Aim. 

Induction grading is conducted using stress relief annealed Epstein samples tested in accordance with ASTM tesl method A 343. Samples are 

secured from each end of the coil and the higher core loss value is used for certification of conformance to product grade guarantees.

Typical single sheet core loss va lues versus test induction for TRAN-COR H CAR LITE and CAR LITE DR are provided on page 10. Typical SRA 

Epstein core loss values versus test induction for TRAN-COR H CARLIlE are provided on page 12. SRA Epstein testing is not applicable to 

TRAN-COR CAR LITE DR products since the domain refinement treatment is eradicated upon annealing at temperatures greater than 600°C. 

The core loss and exciting power of the AK Steel TRAN-COR H grades are determined by magnetic tests performed in accordance with general procedures approved by the 

American Society for Testing and Materials. The follOWing conditions apply: 

1. Resu lts for os·sheared single sheet specimens from fu lly processed material cut parallel to the rolling direction of the coil and tested per ASTM A 804 

2. Density of all grades (7.65 gm/cm3 ) per ASTM A 34 

ASTM A 664 is a grade identification system for electrical steels. While this system has not been widely adopted by manufacturers and consumers of electrical steels, it is used 

in ASTM A 876 to designate various grades of groin oriented electrical stee l. The following is a listing of AK Steel and equival ent ASTM grades: 

AK Steel grades H-O CAR lITE and H-O CARUTE DR are approximately equivalent to ASTM Core Loss Types 23P060 and 23Q054, respectively. 

AK Steel grades H-l CARLITE and H-l CARUTE DR are approximately equivalent to ASTM Core toss Types 27P066 and 27Q057, respectively. 

AK Steel grades H-2 CAR LITE and H-2 CARLlTE DR have no equivalent ASTM Core Loss Type designotion5

ORIENTCORE· HI-B~ LS 

ORIENTCORE ·HI·B·LS is an extra·low core loss. grain'oriented electrical 

steel sheets which has been developed Irom ORIENTCORE· HI·B by 

irradiating the surface with a laser beam to refine Ihe magnellc domain. 

[PRECAUTION IN USE! 

Never use in Ihe wound cores. etc. which will require stress-relief annealing 

that reduces the effect of laser beam irradiation. /I is most suitable for 

use in large stacked cores which will not require stress- relief annealing.

ORIENTCORE· HI-B~ PM 

ZOMH is the product which can achieve low core loss by magnetic domainrefining method. i. e. surface treatment of ORIENTCORE ·HI-S. 

This product can withstand stress-relief annealing(up to approximately 800'C 

in a non-oxidizing atmosphere), therefore ZOMH can be used widely not only for 

large elec tric power transformer but also for various kinds of transformers.
