1 FORGING THE FUTURE NOW

2 The origin of the metallurgical industry in Terni dates back to 1884, closely linked to the spread of steel making on an industrial scale in Italy. This large metallurgical plant, named "Terni" until 1989, was founded in response to a strategic need. The heavy demand for products on the part of the newly created Italian Navy imposed that this industry should be placed in a geographically strategic area, which would become later a key factor in its further development into an integrated and diversified structure. At the end of World War II the Italian metallurgical industry was thoroughly reorganized on a completely new basis: the manufacturing of special products for power generation and industry. Within this framework, the Terni plant was assigned the role which was most appropriate to its experience and to its facilities: the manufacture and transformation of high quality steels. Such activity placed the Terni as it was, Società delle Fucine nowadays, among the few worldwide leading manufacturers capable of producing heavy and medium forgings in a large variety and with advanced manufacturing techniques. Società delle Fucine has carried forward the expertise and innovative will, characteristic of the century old manufacturer, the Terni. Società delle Fucine operational structure is made up of the company headquarters and factory, which are located in Terni (100 Km northeast of Rome), optimally linked by road and rail for domestic communication network and served by Rome and Perugia airports and Civitavecchia and Livorno ports for international communications. Società delle Fucine productive unit covers a sq/m area, manufacturing a wide range of forgings from carbon, high-and mediumalloyed and stainless steels. Società delle Fucine products are destined to primary economy sectors, such as power generation and industry where absolute reliability is required to assure working safety and, at the same time, economic advantages in its management. All quality steels, the development of which stems from a century-old metallurgical experience and their manufacture comply with the latest steelmaking techniques.
