US Steel is temporarily idling its Granite City, Illinois, flat-rolled mill due to the United Auto Workers (UAW) strike. The 1.4mn short tons/yr blast furnace B will be idled, and its product mix will be filled from other steelmaking facilities in Arkansas, Indiana, and Pennsylvania.
The company is executing a risk mitigation plan to ensure melt capacity is balanced with its order book. The UAW began striking at three facilities, one each owned by Ford, General Motors (GM), and Stellantis. A prolonged labor stoppage could cut into US flat-steel demand and other metals like aluminum and copper.
US Steel proposed converting Granite City from steelmaking to pig iron production last year to supply its electric arc furnace operations in Arkansas and Alabama.
