Ferro Silicon Manganese (FeSiMn) is a dual-function ladle and furnace addition that combines manganese alloying with silicon-driven deoxidation in a single charge. The Si fraction (14-22%) scavenges dissolved oxygen to form fluid manganese-silicate inclusions that float into the slag, while Mn (65-72%) raises hardenability and ties up sulphur, reducing FeMn and FeSi consumption per heat. Lower silica activity gives cleaner steel than separate FeMn plus FeSi additions. It is used in EAF and BF-BOF deoxidation, low- and high-Mn structural and manganese steels, alloy and welding-electrode production. Typical EAF dosage runs 0.5-1.2 wt% of the heat, adjusted to tap oxygen and target chemistry. This grade holds C ≤ 2.0%, P ≤ 0.20%, S ≤ 0.03% at 10-60 mm sizing, meeting ASTM A483 / ISO 5447 for consistent recovery. Each lot ships with COA and MTC, XRF/ICP-verified, on multi-regional sourcing with CIF Marmara delivery, Gebze bonded stock, and 20 MT FCL or 5 MT LCL lots.
