GrafTech International Ltd. is a manufacturer of graphite electrode products essential to the production of electric arc furnace (EAF) steel and other ferrous and non-ferrous metals. Its portfolio consists of ultra-high power (UHP) graphite electrode manufacturing facilities. Its graphite electrode manufacturing facilities are located in Calais, France; Pamplona, Spain; Monterrey, Mexico and St. Marys, Pennsylvania. Its product categories include graphite electrodes and petroleum needle coke products. Graphite electrodes are an industrial consumable product used primarily in EAF steel production, one of the two primary methods of steel production and the steelmaking technology used by mini‑mills. Petroleum needle coke is a crystalline form of carbon derived from decant oil, which is the key raw material used in the production of graphite electrodes. Its production process converts decant oil, a byproduct of the gasoline refining process, into petroleum needle coke.
