US Steel Corp announced Tuesday that it will permanently shut down operations at its Hamilton, Ontario, mill at the end of this year.
The integrated mill, which had an annual capacity of 2.3 million tons before it was idled in 2010, will continue its coke-making and steel finishing operations at Hamilton.
CEO Mario Longhi said the Hamilton closure is part of an initiative dubbed "Project Carnegie" that aims to reduce costs by about $50 million a year. In addition to the Hamilton shutdown, the company will close two coke batteries at Gary Works in Indiana, and let certain iron ore supply contracts expire in 2013 and 2014.
