In 1809 the Fabrique de Fer d'Ougrée[note 1] (English: Iron factory of Ougree) was founded, and in 1834 converted into an integrated works.

[1] In 1835 the Société des Charbonnages et Hauts-Fourneaux d'Ougrée (English: Coal and blast furnace company of Ougree) was founded.

[8] The factory in Ougrée became one of the primary hot production sites of the ArcelorMittal Liège division along with works at Seraing and Chertal.

[9] Due to the economic downturn caused by the financial crisis of 2007–2010 blast furnace B temporarily stopped production from spring 2009 to April 2010.

The company cited overcapacity, and uncompetitiveness as reasons for the closure; a report by Syndex commissioned by trade unions contradicted the claims of un-competitiveness, claiming ArcelorMittal's reports used biased accounting unions officials called for the liegeois steel industry to be taken into ownership outside ArcellorMittal to protect it.
