U.S. Steel plans to spend at least $750 million to upgrade its century-old Gary Works steel mill in Gary, Ind. According to the company, the investment will help preserve approximately 3,900 jobs and will allow the company to become more competitive by upgrading technology and giving workers new tools. In March, U.S. Steel announced it was restarting one of two blast furnaces and the steelmaking facilities at its Granite City Works, an integrated steelmaking plant in Granite City, Ill.  

Located on the southern shore of Lake Michigan, Gary Works is U.S. Steel’s largest manufacturing plant, with an annual raw steelmaking capability of 7.5 million net tons. The facility makes sheet products, strip mill plate in coils and tin products.
