en.Wedoany.com Reported - U.S. Steel is planning to invest $2 billion to $2.5 billion to upgrade or build a new hot strip rolling line at its Mon Valley Works in southwestern Pennsylvania's Monongahela River Valley. The project was initially proposed by Nippon Steel in August 2024, with a commitment of at least $1 billion following the completion of the merger between the two companies. The scope has now expanded, and the new rolling mill will not only boost product output, quality, and energy efficiency but also expand the range of steel products the plant can supply to the automotive, appliance, and industrial markets.
David Burritt, CEO of U.S. Steel, said in a statement that the Mon Valley Works is the birthplace of the American steel industry, and this investment shows its best days are still ahead. According to the investment details provided by the company, the new hot rolling mill will be equipped with two reheat furnaces, an upgraded casting process capable of producing thicker, higher-quality slabs, and a new ladle metallurgy furnace. Construction is set to begin later this year, with production expected to start in the second half of 2029.
As part of the investment, U.S. Steel will also build a slag recovery facility to support the new production line, with construction already underway. The company stated that these investments are aimed at supporting steel production in the region for decades to come. According to an economic impact analysis conducted by the Parker Strategy Group, the $2.5 billion plan is expected to generate up to $58 million in state and local tax revenue; the $2 billion plan could contribute up to $1.4 billion to the state's economy, support 5,105 jobs, and generate $46.4 million in state and local tax revenue.
Burritt said the investment protects thousands of high-paying jobs and establishes a world-class facility that will supply steel to American automakers and manufacturers for generations, embodying a commitment to investing in America. The Edgar Thomson plant, which has been operating for over 150 years, is the last integrated steel producer in Pennsylvania with blast furnaces and basic oxygen furnaces, and is an integral part of the Mon Valley Works and other U.S. Steel facilities. The plant was first opened in 1875 by businessman and philanthropist Andrew Carnegie as part of Carnegie Steel; in 1901, he sold the company to banker J.P. Morgan, who merged Carnegie Steel with nine other steel companies to form the foundation of U.S. Steel. The Edgar Thomson plant is currently designated as a National Historic Landmark.
