GPC

GPC

Graphitized Petroleum Coke (GPC) is a recarburizer produced by heat-treating petroleum coke at graphitization temperatures, which orders the carbon into a graphitic lattice. That structure gives fast, high-efficiency dissolution in molten iron and steel and minimal nitrogen pickup — useful where low-N carbon control matters. With F.C ≥ 98.5% and S ≤ 0.05%, GPC raises carbon without loading sulphur, supporting clean nodule formation in ductile iron and consistent matrix carbon in grey iron. It serves ductile and grey iron casting, steel carburization, and brake pad/friction material formulations. Typical recarburizer additions run roughly 0.3-2.0 wt% of charge, set by base carbon and target chemistry, with high recovery from the graphitic structure. The 1-5 mm sizing and ≤ 0.5% ash, V.M, and moisture suit ladle and in-furnace additions with stable yield. Each lot ships with COA and MTC; F.C, S, and ash are verified per shipment. Multi-regional sourcing supports CIF Marmara delivery and Gebze bonded stock in 20 MT FCL. Send your target grade and tonnage for an RFQ.
