United States Steel Corporation

United States Steel Corporation, commonly known as U. S. Steel, is a major integrated steel producer headquartered in Pittsburgh, Pennsylvania. Founded in 1901, the company's core business involves the production and sale of various steel products, along with iron ore and coke production. U. S. Steel is committed to delivering profitable and sustainable steel solutions, with a stated goal of achieving net-zero greenhouse gas emissions by 2050.

The company's diverse product portfolio includes flat-rolled steel such as slabs, strip mill plates, sheets, and tin mill products, as well as tubular steel products like seamless and electric resistance welded casing and tubing. U. S. Steel also produces advanced high-strength steel (AHSS), ultra high-strength steel, and various coated and cold-rolled sheets. These products serve a wide range of critical industries, including automotive, construction, appliance, energy, containers, industrial machinery, and oil and gas, across North America and Central Europe.

In a significant development, United States Steel Corporation was acquired by Japan's Nippon Steel Corporation for $14.9 billion, with the deal finalized on June 18, 2025, making U. S. Steel a wholly owned subsidiary. Nippon Steel has pledged substantial investments, including $1.9 billion for a new direct reduced iron (DRI) facility at U. S. Steel's Big River Steel Works in Osceola, Arkansas, marking the first of its kind in the United States. The acquisition also includes a "golden share" for the U.S. government, providing veto power over certain corporate decisions. David B. Burritt serves as the President and CEO of U. S. Steel.
