Ferromanganese HC

HC FeMn

High carbon ferro manganese (HC FeMn) is a primary manganese unit for steelmaking, used to deoxidize liquid steel and to alloy in manganese for strength and hardenability. Manganese has a higher affinity for oxygen and sulfur than iron, so HC FeMn pulls dissolved oxygen into the slag and ties up sulfur as MnS, countering hot-shortness during rolling. This grade carries Mn ≥ 65% with C ≤ 7.0%, Si ≤ 2.0%, P ≤ 0.30% and S ≤ 0.03%, sized 10-80mm for controlled dissolution in BF-BOF and EAF practice. The 65% Mn floor and capped P suit construction and structural steels, alloy steel, and ladle desulfurization where carbon pickup is acceptable. Typical additions run about 0.3-0.8 wt% of the heat, adjusted to target Mn recovery and residual limits. Conformance is verified by XRF/ICP against ASTM A99 / ISO 5446, with COA and MTC supplied per lot. Multi-regional sourcing supports CIF Marmara delivery and Gebze bonded stock, in 20 MT FCL lots. Send heat size and target Mn for a graded RFQ.
