U.S. Steel Board Greenlights Major $100M and $200M Upgrades at Current Facilities

U.S. Steel announced that its board of directors approved its next phase of capital investment plans. The development marks another step in the partnership between U.S. Steel and Nippon Steel following the Japanese company's nearly $15 billion acquisition.

A $100M Plant Upgrade in Pennsylvania

Investment plans include an“air construction permit” to build a new slag recycler at U.S. Steel's Edgar Thomson site in Pennsylvania, where it conducts basic steel production. The company stated that it would finalize engineering planning after securing permit approval from the Allegheny County Health Department and expects to begin construction on the $100 million project next year.

U.S. Steel noted that the slag recycler would repurpose steelmaking byproducts, including materials used in cement production, while lowering waste and air emissions.

Enhancing the Indiana Hot Strip Mill

The board also approved a $200 million upgrade to U.S. Steel's Gary Works hot strip mill in Indiana, aimed at cutting production costs and expanding premium products, including automotive steel and heavy-gauge line pipe. Gary Works, U.S. Steel's largest plant, features finishing and steelmaking facilities.

U.S. Steel added that these two projects represent a fraction of its other efforts to improve infrastructure, boost capabilities, and modernize facilities.
