AISI: Raw steel production strengthens further
Written by Brett Linton
Domestic mill production ticked up to a new multi-year high last week, the fifth consecutive weekly gain, according to recently published American Iron and Steel Institute (AISI) figures.
Total US raw steel production was estimated at 1,848,000 short tons (st) in the week ending April 18 (Figure 1). This is up 5,000 st, or 0.3%, from the previous week and is now at the highest level recorded since November 2021. Production has strengthened 9% since the beginning of this year.
Last week’s production was 3.2% above the year-to-date (YTD) weekly average of 1,785,000 st, and 9.7% higher than the same week one year ago. YTD production now totals 27,719,000 st, up 5.8% from the same period last year.
The mill capability utilization rate was 80.0% last week, the highest weekly rate recorded since August 2024. Compare this to 79.8% the prior week and 75.0% in the same week of last year. Capability utilization has averaged 77.7% YTD.
Raw production increased week over week (w/w) in three of the five AISI-defined regions:
- Northeast – 133,000 st (up 8,000 st)
- Great Lakes – 525,000 st (up 10,000 st)
- Midwest – 295,000 st (down 16,000 st)
- South – 823,000 st (down 7,000 st)
- West – 72,000 st (up 10,000 st)
