U. S. Steel Secures NanoSteel® Patents to Expand Capabilities of World Class Advanced High-Strength Steel Offerings

PITTSBURGH--(BUSINESS WIRE)--United States Steel Corporation (NYSE: X) today announced the acquisition of the flat rolled sheet patents and trademarks of The NanoSteel Company, Inc. as part of U. S. Steel’s ongoing commitment to offer customers the world’s best selection of advanced high-strength steels, which now includes the most formable high-strength steel available anywhere.

The NanoSteel Company designed and developed patented proprietary alloys which derive exceptional mechanical properties from their nano-scale microstructure, which creates a unique combination of extreme strength with the enhanced formability normally found only in low-strength mild steels. The NanoSteel® grades can be rolled thicker than other high-strength grades and are designed for automotive and heavy industrial applications where higher strength-to-weight ratios are essential.

“We are pleased to offer our customers yet another set of advanced high-strength steel grades that move beyond the boundaries of what was previously possible,” U. S. Steel President and Chief Executive Officer David B. Burritt said. “These products are in line with our Best of Both^SM strategy and complement and expand our already strong offering of advanced high-strength steels like our proprietary 980 XG3^TM steel.”

“We are already in discussions with customers around the world, looking at new applications where this combination of high formability and high strength was not available on a commercial scale until now,” Burritt said.

U. S. Steel has acquired the majority of The NanoSteel Company’s intellectual property and becomes the sole owner and producer of its internationally recognized high-strength steel grades. Other terms of the transaction were not disclosed.
