U.S. Steel

The United States Steel Corporation (NYSE: X), more commonly known as U.S. Steel, is an integrated steel producer with major production operations in the United States, Canada, and Central Europe. The company was the world's 13th largest steel producer in 2010. It was renamed USX Corporation in 1986 and back to United States Steel Corporation in 2001 when the shareholders of USX spun off its steel-making assets following the acquisition of Marathon Oil and Texas Gas in 1982. In 2001 it was still the largest domestically owned integrated steel producer in the United States, although it produced only slightly more steel than it did in 1902.

U.S. Steel is a former Dow Jones Industrial Average component, listed from April 1, 1901 to May 3, 1991. It was removed under its USX Corporation name with Navistar International and Primerica Corporation.
