After REO Motor Car Company, founded by Ransom E. Olds, sold its operations and initiated liquidation proceedings, a group of dissident activist shareholders, noticing the existence of a usable tax loss, successfully challenged the liquidation in a proxy fight in September 1955 and forced REO to take over a tiny nuclear services company called Nuclear Consultants, Inc. in a reverse takeover.

The company was renamed "Nuclear Corporation of America Inc." and relocated to offices in the Empire State Building in New York City. The organization's attempt to recast itself as a nuclear industry services company was unsuccessful, and it followed the example of other companies in the 1950s and 60s by attempting to become a conglomerate, moving its headquarters to Phoenix, Arizona. It made several acquisitions, including the Vulcraft Corporation, a steel joist manufacturer located in Florence, South Carolina. Vulcraft was founded by Sanborn Chase, who died at an early age, leaving the company to his widow. Nuclear purchased Vulcraft from Chase's widow in 1962 and hired F. Kenneth Iverson as general manager. In March 1965, the company again filed for bankruptcy. Iverson, head of the only profitable division, took over as head of the company due to lack of interest in the job from others.^[4]

Iverson reorganized Nucor around its only profitable business, the steel fabricator Vulcraft. All other businesses were either sold or liquidated.^[4]

In 1966, the company moved its headquarters to Charlotte, North Carolina to be closer to its main Vulcraft plant in South Carolina.^[5]

In 1968, unable to get favorable steel prices from American manufacturers and unhappy with the imported steel available at the time, Iverson, a metallurgist by training, extended Nucor vertically into steelmaking by building its first steel bar mill in Darlington, South Carolina.^[6][7]

The company purchased an electric arc furnace, which was far cheaper than the traditional steel blast furnace with a $6 million loan secured by all of the company's assets. Production delays and staffing problems resulted in losses, but earnings soared in 1971 and 1972.

In 1972, the company, recognizing that it was now misnamed, adopted its current title, Nucor Corporation.^[4] That year, it became a public company via an initial public offering.^[8]

In 1988, the company opened its building products division.

In 1989, Nucor opened a facility in Crawfordsville, Indiana, the first mini mill in the world to produce flat rolled steel using thin-slab technology.^[9][10]

In March 2000, a joint venture, owned 47.5% by Nucor, 47.5% by BlueScope, and 5% by IHI Corporation was formed to license Castrip technology.^[11] This technology allowed for continuous casting of sheet steel directly from molten steel without the need for heavy, expensive, and energy-consuming rollers.
