The United States Steel Corporation is an American steel company based in Pittsburgh, Pennsylvania. It is a wholly owned subsidiary of Nippon Steel which maintains production facilities at several additional locations in the U.S. and Central Europe. The company produces and sells steel products, including flat-rolled and tubular products for customers in industries across automotive, construction, consumer, electrical, industrial equipment, distribution, and energy. Operations also include iron ore and coke production facilities.

U.S. Steel ranked eighth among global steel producers in 2008 and 24th by 2022, remaining the second-largest in the U.S. behind Nucor. Renamed USX Corporation in 1986, it reverted to U.S. Steel in 2001 after spinning off its energy assets, including Marathon Oil. In December 2023, Nippon Steel announced a $14.9 billion acquisition of U.S. Steel, retaining its name and Pittsburgh headquarters. The deal faced opposition from the United Steelworkers, the Trump presidential campaign, and the Biden administration, which formally blocked it in January 2025. U.S. Steel and Nippon Steel sued the administration, claiming the block was unlawful. The acquisition was finalized on June 18, 2025, making U.S. Steel a subsidiary of Nippon Steel North America.
