Eti Krom Alloy

ETİ KROM ALLOY

YILDIRIM’s first ferroalloys investment came with FeCr production at Eti Krom in Turkey. Established as a state-owned chrome ore mining enterprise in 1936, Eti Krom has been active in HC FeCr production since 1976. Following YILDIRIM’s acquisition of the company in September 2004, the idle furnaces were revamped and the plant was modernized to meet the growing demand for high quality HC FeCr.

With 4 arc furnaces (2 open type and 2 semi-closed type), Eti Krom’s fully integrated ferrochrome plant is able to utilize the high-grade chrome ore extracted from its own mines. The plant’s high quality HC FeCr production ranks it among the leading manufacturers in the world.

Thanks to its wide variety of raw material supply, Eti Krom is able to deliver tailor-made products for special applications.
