"The transaction - a 50:50 joint venture with NSSMC - was completed for an agreed price of USD 1,550 million plus working capital and net debt adjustment," the world's largest steel-maker said.
In November last year, the two steel-makers had announced that they would form a joint venture to acquire ThyssenKrupp Steel's processing plant in Calvert, Alabama.
The Calvert plant has a total steel processing capacity of 5.3 million tonnes per annum including hot rolling, cold rolling, coating and finishing lines.
The acquirers formed a joint venture and had earlier said that they would finance the deal through equity and debt.
