Import 300mm Hp Grade Graphite Electrode — Buy in wholesale FOB from Supplier in China

The 300mm HP Grade Graphite Electrode from Hebei Ben Hong New Material Technology Co., Ltd. is a high-power carbon electrode with a 300 mm nominal diameter, manufactured from petroleum coke and needle coke with coal pitch as a binder. HP (high power) grade sits between regular power and ultra-high power in the standard electrode classification, offering a balance of current-carrying capacity and thermal shock resistance for electric arc furnace operations. The raw materials undergo calcination, proportioning, kneading, moulding, baking, graphitisation, and precision machining to achieve the density and electrical properties required for steelmaking. The supplier confirms the electrode is intended for electric arc furnace steelmaking and smelting applications where consistent performance under thermal cycling is critical.

Petroleum coke provides the bulk carbon structure, while needle coke contributes the anisotropic crystalline alignment that lowers electrical resistivity and improves thermal expansion behaviour. Coal pitch binder carbonises during baking to lock the aggregate into a cohesive matrix; typical industry baking reaches 800 degrees C to 1,200 degrees C, followed by graphitisation at approximately 2,800 degrees C to 3,000 degrees C in an Acheson or LWG furnace. The resulting article shows low electrical resistance, low coefficient of thermal expansion, and adequate mechanical strength to withstand gripping by electrode clamps and the weight of the column above. Oxidation resistance is moderate compared to UHP grades, reflecting the different needle-coke proportion and graphitisation temperature in HP production.

Steel mills producing carbon steel, alloy steel, and stainless steel in electric arc furnaces are the primary consumers, alongside ferroalloy smelters and foundries running submerged-arc or ladle furnaces. The 300 mm diameter suits medium-power furnaces in the 20-ton to 50-ton capacity range, though exact furnace matching depends on current density and electrode length consumed per ton of steel. Standard export packaging places electrodes on wooden pallets with steel strapping; buyers should confirm pallet dimensions, maximum stack height, and ISPM-15 treatment with Hebei Ben Hong New Material Technology Co., Ltd. HS code 8545.11 applies for customs classification, and origin documentation from Hebei province is standard for Chinese graphite electrode exports.

Hebei Ben Hong New Material Technology Co., Ltd. is located at Room B2506, Huahai Global Plaza, Xinhua District, Shijiazhuang, Hebei 050000, China. The address indicates a commercial-office presence in Shijiazhuang rather than a disclosed production site. The company holds a harbor trust tier. Response metrics show 0.00 percent response rate and zero average response hours, meaning buyers should not rely on rapid automated replies and should follow up by phone or alternative channels if email goes unanswered.

The supplier lists graphite electrodes as their product focus, with material composition and manufacturing stages described in technical detail. No employee count, factory ownership status, annual output, or client references appear in the source data. Buyers should request a business licence, ISO 9001 or equivalent certificate, and a factory audit report if considering volume procurement. Shijiazhuang sits within Hebei province, which has established carbon and graphite manufacturing clusters, though this proximity alone does not confirm production capability.
