The Hauts-fourneaux et aciéries de Differdange, St-Ingbert, Rumelange (French for "Blast furnaces and steelworks of Differdange, St-Ingbert, Rumelange"), generally abbreviated as "Hadir", was a Luxembourgish steel company with Luxembourgish, Belgian and French investors.

It was founded in 1920 from the Deutsch-Luxemburgische Bergwerks- und Hütten-AG, and was taken over by ARBED in 1967.
