The Diameter 250mm UHP 250 graphite electrodes are high-purity carbon-based electrodes designed for electric arc furnaces in steelmaking and ferroalloy production. These electrodes feature a nominal diameter of 250mm and are manufactured to UHP Grade 250 standards, indicating low resistivity and high thermal shock resistance. Each electrode is pre-fitted with threaded nipples for direct connection to adjacent electrodes in the furnace stack.
The material composition is primarily petroleum coke and coal tar pitch, with ash content below 0.5% and true density exceeding 1.80 g/cm³. The electrodes are graphitized at temperatures above 2800°C to achieve optimal electrical conductivity and mechanical strength. Typical resistivity values range from 5.5 to 6.5 μΩ·m, and flexural strength is above 12 MPa, consistent with international UHP standards.
These electrodes are primarily purchased by steel mills in Southeast Asia, the Middle East, and Africa for use in mini-mills and scrap-based production lines. Buyers typically order in full container loads of 15 to 20 metric tons, with packaging in wooden crates or steel bands. Lead time is approximately 4 to 6 weeks from order confirmation, and delivery is usually FOB Qingdao or Tianjin.

Rongxing Group is registered in Linzhang, Handan, Hebei, with a secondary address in Zhengzhou, Henan. The company claims an annual production capacity of 50,000 metric tons of graphite electrodes and 200,000 metric tons of paste electrodes, but provides no factory photos, certifications, or third-party audit reports. The listing does not indicate export experience, ISO status, or any verified client references.
There is no information on workforce size, laboratory facilities, or quality control processes. The supplier has no recorded response rate or response time, suggesting limited buyer engagement. Buyers should treat this as a production facility without public verification and request independent testing reports before placing bulk orders.
This 250mm UHP 250 grade graphite electrode comes pre-fitted with nipples for seamless integration into electric arc furnace operations in steelmaking and smelting facilities. Designed to meet ultra high power performance standards, these electrodes offer superior electrical conductivity and thermal resistance for demanding industrial applications. Stock is available for immediate export with a global manufacturer capable of producing 50,000 MT of graphite electrodes annually, making this a reliable supply chain solution for bulk buyers and importers seeking consistent quality.

Before ordering, verify the batch-specific test report for ash content, resistivity, and flexural strength. Confirm that the electrodes meet ISO 10143 or ASTM B775 standards, and request a certificate of conformity. Check that the nipples are properly threaded and free of burrs or misalignment, as improper fit can cause furnace downtime.
Lead time is typically 4 to 6 weeks after order confirmation. Delivery is usually FOB Qingdao or Tianjin. Incoterms must be confirmed explicitly - buyers should not assume CIF or CFR unless stated. Payment terms are commonly 30% advance, 70% against copy of bill of lading. Request a detailed packing list with individual electrode weights and serial numbers.
Upon arrival, inspect for physical damage, moisture exposure, or corrosion on the nipple threads. Measure the diameter of at least three electrodes per container using a calibrated micrometer. Test the electrical continuity of the nipple-to-electrode connection with a low-resistance ohmmeter. Retain samples from each batch for third-party lab analysis if quality disputes arise.
