United States Steel Corp., Pittsburgh, announces that it 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 part of the company’s Mon Valley Works.


The cutting-edge 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. It will improve the quality and attributes of its downstream products for customers in appliance, construction, and industrial markets.


XG3 Advanced High Strength Steel (AHSS) will also be produced at Mon Valley Works, which will become the principal source. This project, in addition to producing sustainable AHSS, will improve environmental performance and energy conservation, and will reduce the carbon footprint. 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 state-of-the-art 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.


The company expects that the project will result in significant improvements in emissions compared to the existing facilities, including reductions in emissions of Particulate Matter (PM) of approximately 60%, PM10 and PM2.5 of approximately 35%, sulfur dioxide of approximately 50%, and nitrogen oxides of approximately 80%.
