Explore our high-performance welding wires and consumables manufactured for maximum durability, clean finishes, and defect-free welding operations.
Wulian Yuxin Hardware Equipment Co., Ltd.
Established in the industrial hub of Wulian, Rizhao City, Shandong Province, Wulian Yuxin Hardware Equipment Co., Ltd. has evolved from a dedicated local manufacturer to a prominent global exporter of top-grade welding consumables. Across nearly two decades of continuous innovation and market expansion, our footprint has extended to heavy-duty engineering applications worldwide.
Spanning a dedicated 15,000-square-meter manufacturing facility, we integrate advanced wire rod processing lines, heat treatment systems, and automated precision winding machines. This full vertical integration ensures our ability to monitor every stage of production—from the raw steel billet stage to final hermetically sealed vacuum packaging.
Providing high-precision metallurgical solutions to combat weld failures, structural decay, and corrosion under extreme industrial environments.
Modern mega-projects in aerospace, petrochemical processing, and maritime shipping demand zero-defect components. Our 308 Stainless MIG Wires are designed to mitigate intergranular corrosion, maintaining stable arc transfer under intensive heavy production cycles.
For austenitic alloys such as AISI 301, 302, 304, and 308, weld zone sensitization presents severe structural risk. Our wires contain tightly controlled low carbon percentages (<0.03% for ER308L), vastly decreasing the precipitation of chromium carbides at grain boundaries.
Through proprietary surface cleaning techniques, we produce wire with minimal surface micro-abrasions. This leads to friction-free feeding inside robotic liners, minimizing weld defects like spatter, arc interruptions, and premature contact tip wear.

| AWS Classification | C (%) | Cr (%) | Ni (%) | Mn (%) | Si (%) | P/S (%) | Ferrite Number (FN) |
|---|---|---|---|---|---|---|---|
| ER308 | 0.08 max | 19.5 - 22.0 | 9.0 - 11.0 | 1.0 - 2.5 | 0.30 - 0.65 | ≤ 0.03 / 0.03 | 4 - 12 |
| ER308L (Low Carbon) | ≤ 0.03 | 19.5 - 22.0 | 9.0 - 11.0 | 1.0 - 2.5 | 0.30 - 0.65 | ≤ 0.03 / 0.02 | 3 - 10 |
| ER308LSi (High Silicon) | ≤ 0.03 | 19.5 - 22.0 | 9.0 - 11.0 | 1.0 - 2.5 | 0.65 - 1.00 | ≤ 0.03 / 0.02 | 4 - 11 |
Note on Silicon Content: The elevated Silicon (Si) within the ER308LSi alloy improves weld pool wetting, resulting in highly fluid puddle flow. This dynamic produces smooth, flat weld beads with clean tie-ins at the edges, minimizing post-weld grinding in aesthetic structural installations.
Ferrite Number Control: Managing the delta ferrite level is critical for preventing hot cracking. Wulian Yuxin utilizes advanced spectrographic analysis to maintain the delta ferrite within a targeted 3-10 FN range, balancing cracking resistance and mechanical strength under cryogenic service temperatures.
Our stainless steel and carbon welding consumables deliver high tensile and corrosion performance in modern industrial settings.
To serve heavy industries globally, our supply channels adhere to international standards. Wulian Yuxin coordinates directly with overseas engineers and procurement agents, aligning batch runs with specific project requirements.
Every shipment is accompanied by Mill Test Certificates (MTC) conforming to EN 10204 3.1, giving clients complete chemical and physical validation before the product reaches the warehouse.
Why Tier-1 industrial buyers rely on Wulian Yuxin: Our quality controls are 30% stricter than industry baselines.
We source raw wire coils exclusively from premier domestic steel mills. Each melt batch is analyzed for chemistry, impurities, inclusions, and drawability before extrusion.
Equipped with advanced diamond-die drawing machinery, we maintain wire diameter tolerances within ±0.01mm. This tight tolerance reduces erratic friction inside liners and guides.
Every spool is layer-wound under computer control, avoiding crossovers or loops. Consistent wire tension prevents feeding hitches in automated robotic processes.
