Import Carbon Steel Welding Electrodes — Buy in Bulk from Supplier in China

These carbon steel welding electrodes cover multiple AWS and GB classifications, including E4313, E4303, E5003 and E5016, designed for low, medium and high-strength carbon steel applications. The chemical composition is tightly controlled, with carbon content ranging from 0.10% to 0.18%, manganese from 0.32% to 1.60%, silicon up to 0.90%, and phosphorus and sulfur each capped at 0.035% and 0.040%. Tensile strength spans 420 MPa to 490 MPa across the range, with elongation values between 17% and 30%, matching the demands of structural and cosmetic welding tasks.

The electrodes are tailored for specific uses: E4313 suits light-gauge sheet steel, E4303 and E426 are for key structures in low-carbon and low-alloy steels, while E506 variants handle medium-carbon steel and 16Mn low-alloy structures. E506D and E506F are optimized for crack sealing and high-efficiency welding, respectively. Typical industry standards for carbon steel electrodes include a minimum yield strength of 330 MPa to 400 MPa, with impact toughness values often exceeding 27 J at -20°C, though these should be confirmed with the supplier for the exact batch.

Industrial buyers source these electrodes for shipbuilding, pipeline fabrication, heavy machinery assembly and repair work where consistent arc stability and low spatter are critical. Common packaging includes moisture-resistant cartons or plastic drums, with each box containing 5 kg to 25 kg of electrodes. Buyers should confirm packaging specifications, as well as moisture absorption limits (typically below 0.5% for rutile electrodes) to ensure storage compliance. Lead times and incoterms vary by order size, so direct consultation with Elite Import & Export Trade Co., Ltd. is advised.

Elite Import & Export Trade Co., Ltd. operates from Unit 2801, Block B, New World Center in Nanjing, China, as an importer of welding consumables. The company is categorized under the harbor trust tier, indicating a baseline level of verified trade activity. Its profile does not state a response rate or average response time, so buyers should expect to initiate contact directly for inquiries.

The supplier specializes in carbon steel welding electrodes, offering a technical range aligned with AWS and GB standards. No additional certifications, client lists, or production capacity details are provided in the listing. Buyers are encouraged to request verification of manufacturing origins, quality control processes, and batch-specific test certificates before placing orders.
