US Steel's Big River Steel Phase 3 comes online with electric arc furnace
The Osceola, Arkansas complex fires up its newest EAF this week, pushing US Steel's flat-rolled capacity north of 9 million tons and advancing the company's decarbonization targets.
US Steel confirmed that the third electric arc furnace at Big River Steel Works in Osceola, Arkansas fired its first heat this week, marking the final major milestone in a $3.1 billion capacity expansion known internally as Phase 3. The new EAF is rated for roughly 1.6 million tons of liquid steel annually and feeds the site's newest hot-strip mill.
The company said the furnace gives it headroom to serve automotive, appliance, and pipe customers that have been pushed into long lead times since 2023. Chief executive David Burritt told employees the Big River platform will carry the bulk of the company's growth commitments into the next decade while legacy integrated assets in Pennsylvania and Indiana are modernized.
Phase 3 also brings Big River closer to the 40-plus percent scrap ratio that anchors US Steel's 2030 emissions targets. Analysts said the bigger near-term question is whether the company can keep its downstream finishing lines full without cannibalizing pricing in the merchant sheet market.
