U.S. Steel Investing $1 Billion on Facility at Mon Valley

By on
United States Steel Corp., Pittsburgh, will invest more than $1 billion to construct a new sustainable endless casting and rolling facility at its Edgar Thomson Plant in Braddock, Pa., and a cogeneration facility at its Clairton Plant in Clairton, Pa. Both facilities are part of the company’s Mon Valley Works.  

The endless casting and rolling technology combines thin slab casting and hot rolled band production into one continuous process and will make Mon Valley Works the first facility of this type in the United States, and one of only a handful in the world, the company claims.

“This is a truly transformational investment for U. S. Steel.  We are combining our integrated steelmaking process with industry-leading endless casting and rolling to reinvest in steelmaking and secure the future for a new generation of steelworkers in Western Pennsylvania and the Mon Valley,” said David B. Burritt, president and CEO of U. S. Steel. “U. S. Steel’s investment in leading technology and advanced manufacturing aligns with our vision to be the industry leader in delivering high-quality, value-added products and innovative solutions that address our customers’ most challenging steel needs for the future.”

The installation of endless casting and rolling technology will give U. S. Steel a world-class asset that will improve the quality and attributes of its downstream products for customers in appliance, construction and industrial markets, executives claim. With this investment, Mon Valley Works will become the principal source of substrate for the production of the company’s industry-leading XG3 advanced high-strength steel that assists automotive customers in meeting fuel-efficiency standards. This project, in addition to producing sustainable AHSS, will improve environmental performance, energy conservation and reduce the carbon footprint associated with Mon Valley Works.

First coil production is expected in 2022, contingent upon permitting and construction.
As part of the project, U. S. Steel will also include construction of a new cogeneration facility, equipped with emissions control systems at its Clairton Plant, to convert a portion of the coke oven gas generated at its Clairton Plant into electricity to power the steelmaking and finishing facilities throughout U. S. Steel’s Mon Valley operations.
