Santa Cruz produces 5 Mtpa of high quality slab. Of this 40% would be exported to ThyssenKrupp's facilities in Germany and the remainder to a processing plant in Mobile Alabama. Santa Cruz is operated by CSA Siderurgica do Atlantico and is ThyssenKrupp's largest foreign investment. Construction began in September 2006 and ThyssenKrupp originally budgeted US$4.19 billion for its construction. But a series of delays and increases in equipment costs meant that the total project capital cost approached US$9 billion, the equivalent of roughly US$1,740/tonne.
