Ferrofosforo

FeP

Ferro phosphorus (FeP) delivers phosphorus as a controlled, dissolvable unit into iron and steel melts, avoiding the violent reaction and fume losses of elemental phosphorus. In the bath, P partitions into the matrix to raise electrical resistivity and strengthen ferrite by solid solution, while lowering surface tension to improve melt fluidity and mold filling. P also promotes the dense, adherent oxide patina that gives weathering steel its atmospheric-corrosion resistance. Typical use spans weathering (COR-TEN) and free-machining steels, soft-magnetic alloys, and thin-section gray and ductile cast iron. Addition rates are modest, on the order of 0.1-1.0 wt% depending on the target P aim and recovery. This grade analyzes P 23-26%, with Si ≤ 4.0%, Mn ≤ 5.0%, C ≤ 1.0%, and Ti ≤ 1.0%, sized 10-100 mm for predictable dissolution and accurate ladle dosing in EAF and foundry practice. Each lot ships with COA and MTC, drawn from multi-regional sourcing, on CIF Marmara terms via Gebze bonded warehouse, in 20 MT FCL or 5 MT LCL lots. Send your target P range and tonnage for an RFQ.
