Written by Ethan Bernard

Raw steel output in the US ticked up last week, according to the latest American Iron and Steel Institute (AISI) data.

AISI estimated total domestic steel output to have been 1,709,000 short tons (st) in the week ending May 4, up 0.5% from the prior week. However, this was down 2.9% from 1,760,000 st in the same week a year earlier.

The mill capability utilization rate was 77.0% last week, up from 76.6% a week ago but down from 78.2% at this time last year.

As of May 4, year-to-date production stood at 30,259,000 st with a YTD mill capability utilization rate of 76.3%. This is down 2.9% from the same time last year when production was 31,151,000 st and mills were operating at 77.9%.
