The nickname derives from the 1950s when Djurgårdens IF's football division was renowned for their physique and physical training as well as their rough style of play on the pitch. The stripes of the Djurgården jersey made, and still does, it look almost like an iron stove. After this period the team became commonly known as "Järnkaminerna" (The Iron Stoves). The nickname has remained arguably the most popular nickname for Djurgårdens IF, its players and supporters, together with "the blue stripes", until today.
During the 1970s younger supporters organized themselves and in 1981 they formed "Blue Saints", although the first supporters club of Djurgården was DIF Supporters Club, established in 1947. Due to bad publicity, after numerous violent clashes, "Blue Saints" reformed, and in 1997 adopted the name "Järnkaminerna" and undertook an effort to whitewash the supporters club's name. Today "Järnkaminerna" are one of Swedens largest supporters clubs in numbers, and smaller sections are today established outside of Stockholm.
A common shortened form of the supporters club Järnkaminerna is JK.
