GPC – Graphite Petroleum Coke for Steel & Foundry Applications

Inclusive of all taxes

Our Graphite Petroleum Coke (GPC) is a premium, high-purity carbon additive specifically engineered for steel and foundry applications. Produced through the graphitization of calcined petroleum coke at elevated temperatures, GPC boasts an exceptional fixed carbon content ranging from 98% to 99.5%, ensuring superior carbon recovery and metallurgical efficiency. The low sulfur content (≤0.05%) minimizes contamination, making it ideal for improving the quality of ductile iron, gray iron castings, alloy steel, and specialty carbon products. Its excellent electrical conductivity and high absorption rate make it indispensable in electrode manufacturing and carbon raisers. Available in versatile forms including lumps, granules, and powder, our GPC offers consistent particle size and purity, ensuring optimum performance in steelmaking, foundries, and related industries. This product stands out for its ability to reduce impurities and enhance conductivity, contributing to improved metallurgical outcomes and product durability in demanding industrial processes.
