US Steel announced that it will restart the No 8 blast furnace at its Gary Works in Indiana, which has a rated capacity of 1.07 million short tons per year, on August 1 to meet increased demand from contracted business. US Steel said "As a major supplier of steel for the auto industry, Gary Works is restoring this capacity to satisfy the very strong demand we are seeing from key contract customers with the reemergence of the auto industry. This action also supports the continued demand we are experiencing from appliances, packaging and construction."

The No 8 BF was temporarily idled in mid-March amid lower demand resulting from the coronavirus pandemic and related automotive production stoppages.

In late June, US Steel announced the restart of the No. 6 BF at Gary, citing increased customer demand. No 6, which was temporarily idled in late April, has an annual rated capacity of 1.23 million short tons per year

The Gary Works, US Steel's largest mill, has four blast furnaces and produces sheet, strip mill and tin products. The No 14 BF, which has an annual rated capacity of 2.54 million short tons per year has continued to operate, while the No 4 furnace, which has a rated capacity of 1.36 million short tons per year, was idled in March.
