EAST CHICAGO ā€” ArcelorMittal is idling the #4 Blast Furnace at its ArcelorMittal Indiana Harbor steel mill after auto plants nationwide shut down for a deep cleaning to slow the spread of coronavirus.

Much of the steel made at the mill in East Chicago and along Northwest Indiana's lakeshore ends in cars, trucks and SUVs. Industry analysts estimate as much as 50% of the business at integrated mills likeĀ ArcelorMittal Indiana Harbor comes from the automotive industry. NWI,COM
