Labor Day has passed, the sun is starting to set a little earlier each day, and cooler weather has begun to find its way down to many of us across North America. Autumn is just around the corner. And you know what that means for the steel industry… Fall maintenance outages!
SMU has received various reports from multiple sources about the mill outages slated for the rest of the year at North American steel mills. We contacted all the mills for confirmation, with a handful of them confirming, but the remainder quiet. So please note some of the outages listed below are unconfirmed. Contact your mill reps with any questions.
The list below is not comprehensive, but it provides some sense of the scheduled outages and the production capacity that will be unavailable this fall.
Removing the 21-day outage at SSAB’s plate mill in Alabama reveals an estimated production loss of approximately 571,781 short tons of sheet products across US mills this fall. Contacts tell SMU this total is far below what is typical for fall maintenance outages.
Additionally, there are also a couple of outages coming in 2026 to be aware of:
- JSW Steel USA: Two-week outage at Mingo Junction, Ohio, mill in January.
- U.S. Steel: 100-day outage for reline of No. 14 blast furnace at Gary Works in Indiana in Q1’26. This is the company’s largest blast furnace, with a daily ironmaking capacity of 7,450 st.
If you know of any other upcoming outages or changes to the list above, please contact laura@steelmarketupdate.com.
Editor’s note: This story and chart have been updated to show corrected estimated production loss totals.
