Domestic mills continue to produce record volumes of steel, according to the latest figures released by the American Iron and Steel Institute (AISI). Last week, raw steel output stood at the second-highest weekly total recorded in the past three years. Mill output has trended higher since April, increasing in six of the last eight weeks.
Through the week ending June 14, domestic steel mill production was estimated to be 1,783,000 short tons (st) (Figure 1). Output eased by 2,000 tons, or 0.1%, from the previous week, when production was at the highest since May 2022, according to AISI’s data.
Last week’s production was 5.5% above the year-to-date (YTD) weekly average of 1,690,000 st and 4.7% higher than the same week a year ago.
The overall mill capability utilization rate was 79.4% last week. This was down slightly from 79.5% the previous week (the highest rate recorded since September 2024) but up from 76.7% one year ago.
YTD production totals 39,855,000 st with a capability utilization rate of 75.5%. This is just 13,000 st (<0.1%) below the same period of 2024.
Raw production increased week over week (w/w) in three of the five AISI-defined regions:
- Northeast – 129,000 st (up 1,000 st w/w)
- Great Lakes – 556,000 st (up 21,000 st)
- Midwest – 253,000 st (up 1,000 st)
- South – 780,000 st (down 22,000 st)
- West – 65,000 st (down 3,000 st)

SMU Survey: Sheet and plate lead times stabilize
Sheet and plate lead times saw minor shifts this week, according to SMU’s latest market survey. Sheet times have inched up over the last month but remain within days of multi-year lows, as they have since May. Plate lead times have bobbed within a tight range for months, hovering roughly a week longer than this time last year.
