Copper-Free Solid Wire
(18Cr-12Ni-2Mo ultra-low carbon, corrosion-resistant)
GJ-ER316L is an 18% chromium - 12% nickel - 2.5% molybdenum ultra-low carbon austenitic stainless steel solid wire strictly complying with AWS A5.9 ER316L. The molybdenum addition significantly improves resistance to pitting and crevice corrosion, especially in chloride-containing environments.
Superior Pitting Resistance: 2.0-3.0% Mo content provides excellent resistance to pitting and crevice corrosion in chloride and acidic environments.
High-Temperature Strength: Molybdenum improves elevated-temperature strength and creep resistance for moderate high-temperature service.
Low Carbon Advantage: <=0.03% C prevents sensitization, maintaining corrosion resistance after welding without post-weld heat treatment.
With Ar+2%O2 shielding: For welding 316/316L in marine equipment, desalination plants, and chemical processing vessels.
With 98%Ar+2%CO2: For pharmaceutical equipment, food processing, and pulp/paper industry components requiring molybdenum-alloyed corrosion resistance.
For coastal structures: Suitable for welding stainless steel in coastal and offshore applications where saltwater exposure is a concern.

Moisture control is critical for submerged‑arc welding fluxes. Our standard packaging is 25‑kilogram multi‑layer kraft paper bags lined with heavy‑duty moisture‑proof plastic bags. For extreme environments or ultra‑low hydrogen requirements (such as H5 grade), we can also provide custom heavy‑duty aluminium foil vacuum packaging. All goods are stacked on wooden pallets and tightly wrapped with multiple layers of industrial shrink film to ensure 100% dryness upon arrival at the port.
No. For High-Grade Oil & Gas pipeline fabrication (such as API X60 to X70), standard neutral fluxes like 301 or active fluxes like 501 are not suitable, as they cannot guarantee the required extreme low-temperature impact toughness. You must use our dedicated pipeline-grade Fluoride-Basic agglomerated flux, GJ-101Q (or GJ-101G), combined with Mo/Ni-alloyed wires (e.g., EA2 or S3Ni1Mo).This combination ensures zero loss of alloying elements and guarantees impact values of ≥27J(or much higher) at -40°C to -50°C.
Our standard MOQ for international orders is normally 5 tons per item. For a full 20‑foot FCL container, the loading capacity is usually 24 tons subject to container space constraints, and it can reach 27 tons without pallets. A 40HQ high‑cube container can hold a maximum of 28 tons. Backed by our robust production capacity, we can finish production, quality inspection and packaging within 7‑10 days upon receiving the deposit, and deliver the goods to major Chinese ports such as Qingdao Port or Tianjin Port.
Yes! We fully understand that re-baking costs time and electricity. For customers who want to skip this step, we highly recommend selecting our Heavy-Duty Aluminum Foil Vacuum Packaging. The flux is vacuum-sealed immediately after high-temperature manufacturing. When you open the bag in your workshop, the flux is in a 100% factory-dry state and can be poured directly into the welding hopper for immediate use.
For structural steel with surface impurities like rust, oil, or mill scale, standard neutral or high-basic fluxes will likely cause porosity. You need our GJ-501A (Aluminate-Rutile Active Flux). It features a highly active deoxidizing slag system that offers exceptional tolerance to surface contaminants. This allows you to achieve flawless, X-ray quality welds at high speeds without rigorous pre-weld grinding, significantly boosting your shop floor efficiency.
