The volume of raw steel produced by US mills inched higher last week, according to the American Iron and Steel Institute (AISI). After steadily increasing in April and May, domestic mill output stabilized in early June and has remained historically strong since.
For the week ending July 12, raw steel production rose by 2,000 short tons (st), or 0.1%, week over week (w/w) to an estimated 1,783,000 st (Figure 1). This rate was just 4,000 st shy of the three-year high recorded in mid-June.
The latest production figure was 4.7% above the year-to-date (YTD) weekly average of 1,703,000 st and 5.1% higher than the same week one year ago. YTD production now totals 46,985,000 st, up 0.7% from the same period of 2024. Prior to June, 2025 output had been trailing last year.
The mill capability utilization rate rose to 78.7% last week, similar to the previous week (78.6%) but higher than the same week last year (76.4%). The capability utilization rate has averaged 76.1% so far this year.
Raw production decreased week over week (w/w) in three of the five AISI-defined regions:
- Northeast – 121,000 st (down 2,000 st w/w)
- Great Lakes – 570,000 st (up 7,000 st)
- Midwest – 233,000 st (up 2,000 st)
- South – 790,000 st (down 1,000 st)
- West – 69,000 st (down 4,000 st)
Editor’s note: The raw steel production tonnage provided in this report is estimated and should be used primarily to assess production trends.
