AISI: Weekly raw steel production slips
Written by Brett Linton
The volume of raw steel produced by US mills eased last week, according to the latest figures from the American Iron and Steel Institute (AISI). Prior to this month, output had remained historically strong since June.
AISI estimated domestic production was 1,740,000 short tons (st) in the week ending Nov. 1, down 7,000 st (0.4%) from the previous week (Figure 1). Output has generally trended lower since August, after reaching a three-and-a-half-year high of 1,800,000 st. The latest rate marks the second-lowest production figure since May.
Last week’s production was 0.8% above the year-to-date (YTD) weekly average of 1,725,000 st and 9.2% higher than the same week a year earlier. YTD production now totals 75,470,000 st, up 3.0% from the same period last year.
The mill capability utilization rate was 76.0% last week, down from 76.3% the week prior but above the 71.7% rate seen this time last year. Capability utilization has averaged 77.0% YTD.
Raw production decreased week over week (w/w) in three of the five AISI-defined regions:
- Northeast – 122,000 st (down 3,000 st)
- Great Lakes – 540,000 st (up 2,000 st)
- Midwest – 251,000 st (up 15,000 st)
- South – 773,000 st (down 12,000 st)
- West – 54,000 st (down 9,000 st)
