The AWS E310-16 (equivalent to China's GB A402) is not merely a consumable; it is a critical component in the structural integrity of high-temperature systems. Composed of 25% Chromium and 20% Nickel, this lime-titania type electrode is designed for welding stainless steels of the same composition, such as AISI 310S, which are frequently subjected to service temperatures exceeding 1000°C. In the realm of industrial growth, the demand for E310-16 has surged, driven by the expansion of the petrochemical, furnace manufacturing, and power generation sectors.
China has evolved from a high-volume producer to a high-quality manufacturing hub. The competitive advantages of sourcing E310-16 from a leading Chinese supplier include:
Our proximity to raw material sources like high-purity Rutile sand and specialized Ferro-alloys ensures consistent chemical composition and reduced lead times.
Top factories in Shijiazhuang utilize advanced laboratories to refine the coating formula, ensuring a stable arc, minimal spatter, and easy slag removal—critical for complex welds.
Automated production lines allow for massive output without sacrificing the precision required for AWS and GB international standards.
Founded in 2007, Shijiazhuang Tianqiao Welding Materials Co., Ltd is located 30 kilometers southwest of Shijiazhuang. Our facility is strategically positioned just 20 kilometers from the 107 national highway, ensuring seamless logistics. We possess a formidable technical force and complete product testing equipment to maintain unwavering product quality.

US, Europe, South America, Australia, Africa, Middle East, and Southeast Asia.
In the context of the global "Energy Transition," the role of high-alloy welding consumables like E310-16 has evolved. For instance, in Hydrogen production facilities where high-temperature electrolysis is utilized, the corrosion resistance and thermal stability of E310-16 become indispensable. As a leading China E310-16 Factory, we don't just sell rods; we provide metallurgical solutions. This includes customized flux adjustments to meet specific client requirements for ductility or tensile strength at cryogenic temperatures.
Ensures consistent chemical transfer during the arc process.
Specialized baking process prevents hydrogen-induced cracking.
Batch-specific chemical analysis reports provided for every order.
E310-16 contains significantly higher Nickel (20%) and Chromium (25%) content. While 308L is for general-purpose 18/8 stainless and 309L is for joining dissimilar metals, E310-16 is specifically engineered for sustained high-temperature service and maximum oxidation resistance.
Yes, the "-16" suffix indicates a lime-titania coating which allows the electrode to operate efficiently on both Alternating Current (AC) and Direct Current Reverse Polarity (DCEP).
To ensure reliability, electrodes must be stored in a dry environment. If exposed to moisture, they should be re-baked at 250°C-300°C for 1 hour before use to ensure the integrity of the arc and deposited metal.
