History and when Companhia Siderúrgica Nacional was founded
Companhia Siderúrgica Nacional was founded in 1941 as part of Brazil’s national industrialization strategy. Supported by diplomatic agreements with the United States during World War II, the company was designed to supply steel for infrastructure, manufacturing and defense.
In 1946, the Presidente Vargas steel mill began operations, becoming the first large integrated steel plant in Latin America and a crucial driver of Brazil’s postwar economic expansion.
In the 1950s and 1960s, CSN expanded production capacity and played a strategic role in developing industrial sectors including automotive, construction, machinery, shipbuilding and heavy infrastructure.
Its output supported major national projects such as highways, railways, hydroelectric plants and manufacturing complexes.
During the 1980s, the company faced economic pressures, inflationary instability and the need for modernization. In 1993, CSN was privatized, marking a pivotal transition from a state-owned enterprise to a competitive, efficiency-driven corporation.
Privatization led to restructuring, modernization of mills, cost reductions and expansion of new business areas.
In the 2000s, CSN broadened its presence through mining expansion, entry into the cement industry and acquisition of logistics assets including ports and rail infrastructure.
The development of Casa de Pedra Mine strengthened vertical integration and enabled greater export capacity, making mining one of the company’s core profit drivers.
From 2010 to 2020, the company invested in technology upgrades, operational efficiency and sustainability. It expanded steel-production capabilities, strengthened logistics, and reinforced its position in the global iron-ore market.
Between 2020 and 2024, CSN navigated significant commodity-price volatility while benefiting from strong demand for iron ore and recovering steel markets.
The company advanced its capital-allocation strategy, reduced leverage, expanded cement operations and intensified investments in environmental technology and energy efficiency. Logistics integration continued to play a critical role in competitiveness and margin expansion.
By 2024, CSN had consolidated its role as a major industrial group in Latin America, operating across multiple segments with strong vertical integration and substantial presence in global commodity markets.
