Severstal Columbus, LLC, formerly known as SeverCorr Corporation, was founded in April 2005 by a group of steel executives including former Nucor Corporation CEO John Correnti. It specializes in "mini-mill" plants, designed to recycle steel into new products suitable for the automobile industry. Its first plant outside Columbus, Mississippi, across from Golden Triangle Regional Airport was completed in August 2007 at a cost of $980 million, and shipped first steel in September of that year. The company is a wholly owned subsidiary of the Russian steel company Severstal. In 2008 the company began a $500 million expansion that will double the mill's size and output to 3.4 million tons by the end of 2011. The expansion will increase employment by 93 people in addition to the 545 already at work.
The plant is a major tenant of the Mississippi Steel Technology Center (MSTC).
