AISI: Output remains low as raw steel production slips

Written by Brett Linton

The volume of raw steel produced by US mills slipped last week, according to the American Iron and Steel Institute (AISI). Weekly production has hovered in this territory for the last two months and is at the sixth lowest rate of this year.

Total raw steel output was estimated at 1,638,000 short tons (st) in the week ending Nov. 30. Mill production declined by 17,000 st, or 1.0%, from the previous week. Recall that raw production fell to a 20-month low of 1,606,000 st in mid-October (Figure 1). 

Production last week was 3.9% lower than the year-to-date weekly average of 1,705,000 st. It is 2.9% less than the same week last year, when mill output totaled 1,687,000 st. 

Last week’s mill capability utilization rate was 73.8%. That’s down from the week prior (74.5%) but up from this time last year (73.4%).

Year-to-date production now totals 80,517,000 st at a capability utilization rate of 75.8%. This is 2.3% less than the same period of last year, when 82,422,000 st had been produced at a capability utilization rate of 76.1%.

Weekly production by region is as follows (weekly changes shown in parentheses):

  • Northeast – 127,000 st (up 2,000 st)
  • Great Lakes – 544,000 st (down 26,000 st)
  • Midwest – 227,000 st (up 14,000 st)
  • South – 690,000 st (down 4,000 st).
  • West – 50,000 st (down 3,000 st)
