History and Background
Founding and Early Years
CSN was founded on 17 October 1955 by the Chilean government under the administration of President Carlos Ibáñez del Campo. The impetus for the creation of a national steel industry stemmed from the country's need to reduce dependency on imported steel and to support domestic construction, mining, and shipbuilding sectors. Initial capital investment was provided by the state, and the company began operations with a modest blast furnace and basic rolling mills. During the 1960s and 1970s, CSN expanded its production capacity through the construction of additional furnaces, the acquisition of technology licenses from European manufacturers, and the establishment of a comprehensive logistics network that leveraged Chile’s extensive port infrastructure.
Privatization and Modernization
The political and economic reforms of the early 1990s, driven by the transition to a market economy, led to a significant restructuring of Chile’s state enterprises. In 1994, CSN underwent a privatization process in which the state sold a majority stake to private investors while retaining a minority share. This transition was accompanied by an investment program that modernized the mill’s equipment, incorporated automation systems, and introduced environmental control technologies. Subsequent years saw the expansion of the product line, including the introduction of high‑grade specialty steels and the development of a recycling division that processed ferrous scrap. The privatization effort positioned CSN as a competitive player in the global steel market, enabling the company to diversify its customer base and enter new markets.
