US Steel plans to invest up to $2.5bn in upgrades for its Mon Valley Works manufacturing facilities south of Pittsburgh.
The project will add a new state-of-the-art strip mill and replace the 87-year-old strip mill at the Edgar Thomson Plant in Braddock, Pennsylvania, as part of an expansion.
Nippon Steel, which acquired US Steel in a $15bn deal last year, said the Mon Valley work will generate $58bn in state and local tax revenue in the coming years.
Nippon Steel originally pledged to invest no less than $1bn for Mon Valley Works back in August 2024
The company plans to invest $11bn in all of US Steel's US operations by 2028.
