US raw steel production ticked up in the week ending on Sept. 6 after a decrease the week before, according to the most recent data from the American Iron and Steel Institute (AISI).
Domestic mills produced 1,795,000 short tons (st) last week, up 1.5% from a week earlier. It also marks a 7.7% rise from the 1,667,000 st produced in the same week last year.
The capability utilization rate was 79.2% last week, up from 78.1% the previous week, but up from 79.2% a year earlier.
Adjusted year-to-date production (YTD) through Sept. 6 was 61,461,000 st at a capability utilization rate of 77%. That’s a 1.9% jump from 60,339,000 st at 76.4% during the same time last year.
Here are the raw production figures week over week (w/w) in the five regions defined by AISI:
