Specimen Stock printed by American Bank Note Company.

United States Steel Corporation, more commonly known as U.S. Steel, is an American integrated steel producer headquartered in Pittsburgh, Pennsylvania, with production operations primarily in the United States of America and in 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. It was the eighth-largest steel producer in the world in 2008. By 2022, the company was the world's 24th-largest steel producer and the second-largest in the United States behind Nucor Corporation. Though renamed USX Corporation in 1986, the company was renamed United States Steel in 2001 after spinning off its energy business, including Marathon Oil, and other assets, from its core steel concern. Pending regulatory and shareholder approval, U.S. Steel would be acquired by Nippon Steel, Japan's largest steel producing company, for US$14.1 billion. The deal, announced in mid-December 2023, would retain U.S. Steel's name and headquarters in Pittsburgh. It was opposed by the United Steelworkers, the Trump campaign, and the Biden administration. As of September 2024, the Biden administration was still set on blocking the proposed acquisition.
