AK Steel Launches TRAN-COR® X — New Grain Oriented Electrical Steel for Power Transformers

May 30, 2018

WEST CHESTER, Ohio, May 30, 2018 (GLOBE NEWSWIRE) -- AK Steel (NYSE:AKS) announced the introduction of its new TRAN-COR® X high permeability grain oriented electrical steel (GOES) product family for use in high and ultra-high voltage power transformers.  High permeability GOES products represent the most technologically-advanced and highest-efficiency electrical steels in the world. 

AK Steel is the only manufacturer of GOES products in North America, which it sells to customers in the U.S. and around the globe.  The new TRAN-COR X electrical steel represents an important step improvement beyond the company’s current, world class TRAN-COR® H product.  This will help power transformer manufacturers design to higher levels of efficiency while reducing greenhouse gas emissions due to energy loss in electricity transmission and distribution.

“AK Steel is excited to introduce this new family of high permeability grain oriented electrical steel, which represents one of the highest efficiency products available in the world,” said Roger Newport, Chief Executive Officer of AK Steel.  “This product enables our customers to improve the overall energy efficiency of the transformers they produce.”

TRAN-COR X provides transformer manufacturers a significant improvement in efficiency over conventional high permeability GOES at the same thickness.  This avoids the use of harder to process thinner steels and allows transformer manufacturers to maintain production efficiencies while still improving transformer performance.
