Steel Market Update sources report that U.S. Steel plans to idle the #1 blast furnace at Mon Valley Works by the end of this week. The furnace, located at the Edgar Thomson Plant, has a daily capacity of 3,460 tons and would leave only the No. 3 furnace at the facility operational at 3,100 tons per day.
The Gary Works #6 BF also will be taken offline, sources say. If verified by U.S. Steel, the company would have just three furnaces operational with a total daily capacity of 15,900 tons per day.
- No. 3 Mon Valley—3,100 tons/day
- No. 14 Gary Works—9,200 tons/day
- Granite City B—3,600 tons/day
When asked for confirmation of the shutdowns, a spokesperson for U.S. Steel replied, “We do not comment on rumors or speculation.”
