It has corporate offices in Monclova, Coahuila, in the center of the Mexican state of Coahuila, 155 miles from the United States border. History. Teódulo Flores Calderon donated the land to AHMSA, later Harold Rudolph Pape founded Altos Hornos de Mexico in 1942 in Monclova, Coahuila for its proximity to the border, with the mines of iron located in the same state and Chihuahua, as well as with coal, located in the carboniferous region of Coahuila. Between 1944 and 1948 , the production increased from 40,000 to 100,000 tons of liquid steel per year. In 1960, the smelter increased its capacity to 2 million tons of liquid steel per year, with this being consolidated as the largest company industry in Latin America. Throughout the decade of the '70s and after several expansions, the company achieved production of 3.75 million tons per year. In the decade of the '80s, AHMSA is nationalized by the federal government and went through several crises. In 1991, AHMSA was privatized and acquired by GAN (North Steeler Group). In 2005, the company began an upturn in production . Alonso Ancira, the owner and president of "Altos Hornos", was arrested by the Interpol in connection with the 2014 sale of a fertilizer plant to PEMEX, the Mexican-state oil company, on May 28, 2019.
