Which US State Produces the Most Steel in 2025?

Quick Takeaways

• Pennsylvania still leads the nation, delivering about 12 million tons of steel in 2024‑25.
• Indiana and Ohio round out the top three, each contributing roughly 10 million tons.
• State policies, logistics hubs, and legacy mill infrastructure drive the rankings.
• Both Nucor and United States Steel Corporation dominate the high‑output plants.
• Future growth will hinge on green‑steel initiatives and workforce development.

Why State‑by‑State Steel Data Matters

When analysts talk about US steel production, they’re really looking at a patchwork of regional economies, supply‑chain decisions, and policy incentives. Knowing which state makes the most steel helps investors spot where new capacity might appear, tells policymakers where to target infrastructure upgrades, and guides job‑seekers toward stable career paths.

How We Measure State Production

The primary source for state‑level figures is the U.S. Department of Commerce which publishes annual steel output by state via the Census of Manufactures. The data are broken down by steel mill a facility that transforms iron ore or scrap into finished steel and then aggregated to the state level.

For the most recent year (2024‑25), the figures are expressed in metric tons. Conversions to short tons (1 metric ton = 1.10231 short tons) are shown where it helps readers compare with older reports.

Top Five Steel‑Producing States in 2024‑25

What Gives Pennsylvania Its Edge?

Two factors keep Pennsylvania on top:

1. Legacy infrastructure. The state inherited massive plant footprints from Bethlehem Steel and US Steel during the 20th century. Those sites were modernized rather than abandoned, preserving capacity.
2. Logistics advantage. Proximity to the Great Lakes, the Port of Philadelphia, and a dense rail network reduces shipping costs for both raw inputs and finished coils.

According to the American Iron and Steel Institute the leading trade association for U.S. steel producers, Pennsylvania’s mills also benefit from a skilled labor pool that dates back generations.

How Indiana and Ohio Compete

Indiana’s rise is tied to flat‑rolled steel for automotive OEMs. Nucor’s mini‑mill model-using electric‑arc furnaces fed by scrap-allowed rapid expansion with lower capital costs than traditional blast‑furnace plants.

Ohio, meanwhile, leans on both flat‑rolled and structural steel. The state’s central location makes it a natural distribution hub for the Midwest, which houses many construction projects.

Both states receive generous tax credits for “green‑steel” projects. The World Steel Association global body tracking steel industry trends reports that these incentives have spurred a 15 % increase in electric‑arc furnace capacity across the Midwest since 2020.

Impact of Green‑Steel Initiatives

Carbon‑neutral steel is becoming a competitive differentiator. States that offer renewable‑energy access (e.g., Indiana’s wind farms, Texas’s solar grids) attract new “green‑steel” projects.

For example, Nucor’s Portage plant in Indiana announced a $250 million investment to replace coal‑derived electricity with wind power, aiming for a 30 % emissions cut by 2030.

These investments are tracked by the Cleveland‑Cliffs a major U.S. iron‑ore miner and steel producer, which reports that green‑steel output now accounts for roughly 8 % of its total U.S. production.

What the Future Holds

Three trends will likely reshape the state rankings over the next decade:

• Decarbonization funding. Federal and state grants for hydrogen‑based direct reduction will favor states with existing hydrogen corridors, like Texas and Pennsylvania.
• Automation and workforce up‑skilling. Plants that adopt AI‑driven process control can produce more steel with fewer workers, influencing labor‑intensive states.
• Export‑oriented capacity. As Asia diversifies its supply chain, U.S. coastal states (e.g., California, Georgia) could see new investment, but the interior belt states will retain the bulk of domestic consumption.

For now, if you’re looking for the strongest steel‑producing market in the U.S., Pennsylvania remains the lead, closely followed by Indiana and Ohio.

Quick Checklist for Stakeholders

• Investors: Prioritize Pennsylvania‑based mills for stable cash flow; watch Indiana for high‑growth, green‑steel opportunities.
• Policy makers: Strengthen rail and Great Lakes ports in PA; expand renewable‑energy incentives in the Midwest.
• Job seekers: Target skilled‑welding and furnace‑operation roles in PA, IN, and OH; consider certifications in electric‑arc technology.
• Suppliers: Align logistics to the Midwest rail hub to cut transport costs.
