Charlotte, North Carolina-based Nucor Corp. has demonstrated a willingness and ability to enter new business areas when it identifies appropriate opportunities. Nucor once was known as Nuclear Corp. of America and is a successor company of the former REO (Ransom E. Olds) Motor Co. In the closing three decades of the 20th century, Nucor selected recycled-content electric arc furnace (EAF) steelmaking as the focus of its investment and growth strategy.
