Mills Schedule Maintenance in Q4

Written by Sandy Williams

U.S. steel mills have numerous maintenance outages planned between now and the end of the year. The list below was compiled from anecdotal reports from service centers, as mills usually don’t comment on such outages for competitive reasons. These outages are generally routine and short of duration. Individually, they are unlikely to have much impact on buyers. But, given the unusual market conditions resulting from the COVID pandemic, they may have some small cumulative effect on steel supplies, and thus perhaps on prices. With steel prices on the rise, buyers may want to take these temporary outages into consideration as they time their fourth-quarter purchases.
