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 BothSM strategy and complement and expand our already strong offering of advanced high-strength steels like our proprietary 980 XG3TM 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.
