Nippon Steel is restructuring operations among plants in Indiana and Pennsylvania, while ramping down production in Illinois.
U.S. Steel confirmed that it will quit shipping steel slabs into Granite City this November — and instead process them in Indiana and Pennsylvania.
“This commercial decision allows U.S. Steel to maintain future flexibility, while maximizing our domestic production footprint,” the company said in a statement. “This option avoids challenging product mixes at each facility, impact on customer orders, and extensive cost inefficiencies.”
