Explore our core industrial welding products, manufactured to rigorous international quality control standards.
In modern industrial fabrication, Tungsten Inert Gas (TIG) welding is preferred for applications requiring supreme metallurgical integrity and aesthetic cleanliness. The 316 stainless steel TIG filler rod (specifically under AWS A5.9 classification ER316L) is the standard for joining similar alloys. Featuring 2% to 3% Molybdenum (Mo) alongside high Chromium (Cr) and Nickel (Ni) content, the alloy forms a robust passive layer that resists aggressive environment corrosion, including chlorides, organic acids, and sulfurous gases.
The addition of molybdenum in the 316 alloy family provides resistance to localized pitting and crevice corrosion. The carbon content in the "L-grade" (Low Carbon) filler rods is strictly controlled below 0.03% to prevent chromium carbide precipitation at the grain boundaries during welding. This protects the weld zones against intergranular corrosion (weld decay) without needing post-weld heat treatment.
For procurement directors and welding engineers, sourcing filler wires that meet the exact chemical composition limits of ASME SFA-5.9 and EN ISO 14343-A is critical. Even minor variations in the elemental balance can significantly affect the delta ferrite level, which directly influences susceptibility to hot cracking during solidification.
| Element | AWS ER316L Requirement (%) | Yuxin Certified Control (%) |
|---|---|---|
| Carbon (C) | ≤ 0.030 | 0.015 - 0.022 |
| Chromium (Cr) | 18.0 - 20.0 | 18.5 - 19.2 |
| Nickel (Ni) | 11.0 - 14.0 | 11.5 - 12.5 |
| Molybdenum (Mo) | 2.00 - 3.00 | 2.10 - 2.40 |
| Manganese (Mn) | 1.0 - 2.5 | 1.60 - 1.85 |
Pioneering Excellence in Welding Solutions Since 2004
Established in Wulian, Rizhao City, Shandong Province, Wulian Yuxin Hardware Equipment Co., Ltd. has grown from a locally excellent manufacturer to a globally recognized producer of premium welding consumables. With our own 15,000-square-meter production facility and advanced manufacturing equipment, we proudly maintain complete control over our production processes, ensuring consistent quality across our entire product range.
Over the past two decades, we have focused on technological innovation, refining raw wire preparation, advanced drawing, surface cleaning, and automated packaging. Our team provides global industrial projects with stable metallurgy, high feedability, and robust performance in extreme service conditions.
Analyzing the supply chain, production technology, and quality systems that make Wulian Yuxin a preferred global manufacturer.
We source raw steel from premier national mills. Using strict incoming material inspections, our in-house lab tests carbon levels, trace elements, and inclusions to guarantee consistent behavior arc after arc.
Our drawing process uses multi-pass diamond dies and specialized cooling lubrication. This minimizes surface micro-cracking and maintains dimensional tolerances that are 30% stricter than ISO standards.
Our post-drawing cleanup line includes multi-stage ultrasonic washing to remove residual drawing soaps, grease, and oxides. Clean surfaces are essential to prevent weld porosity in TIG processes.
Equipped with advanced production systems and quality verification systems, our Wulian factory operates at high standards of efficiency.
Connecting with clients globally to share our research and products in welding materials.
Due to its high performance, the 316 TIG filler rod is used across many critical industries:
Used to weld ship fittings, heat exchangers, ballast tanks, and desalination piping. The molybdenum content protects joints against chloride-induced stress corrosion cracking.
Used for joining vessels, pumps, valves, and transport lines containing acidic chemicals, chlorine compounds, and organic solvents. The low carbon content maintains strength without sensitization.
Maintains sanitary surfaces in dairy, brewing, and food processing lines. The TIG process produces clean welds that prevent contamination and bacterial growth.
Our products are used in demanding engineering applications, proving their reliability in the field.
Today, our products are trusted by industrial clients in over 20 countries worldwide. From major construction projects in Germany to manufacturing plants in Vietnam, our welding solutions form invisible bonds that hold critical infrastructure together. Our export markets include:
