US Steel, a subsidiary of Nippon Steel, announced on October 22 that it will invest about $3 billion (about ¥470 billion) in the Edgar Thomson plant at its Mon Valley Works in Pennsylvania.
The upgrade, which includes new facilities, will raise annual production capacity by about 60% to roughly 3.5 million tons.
New Hot Strip Mill Targets 2029 Start
The US Steel board approved the investment earlier this month. The company will build a new hot strip mill at the site to supply a broad range of demand, including automobiles, home appliances, and the energy sector. Operations are scheduled to begin in 2029.
US Steel President and CEO David Burritt said in the announcement, "We are bringing world-class technology to the Mon Valley, creating new capabilities for our customers, and strengthening American steelmaking for the next generation."
Largest Step Yet in Nippon Steel's US Plan
US Steel said the investment's impact will extend across the state. It estimates the project will create thousands of jobs and increase tax revenue, generating up to $1.7 billion in economic benefits over the next three years.
Nippon Steel completed its acquisition of US Steel in June 2025 and plans to invest $11 billion in the United States by 2028. The Mon Valley project is the largest single investment so far.
