Import 304 3mm Stainless Steel Welding Wire — Buy in wholesale FOB from Supplier in China

Wuqiang Huili Fiberglass Co., Ltd. supplies 304 stainless steel welding wire at 3.0mm diameter, positioned for MIG and TIG welding processes in industrial fabrication. The wire is drawn from austenitic 304 grade, containing nominally 18-20 percent chromium and 8-10.5 percent nickel with carbon limited to 0.08 percent maximum under ASTM A580. This composition provides oxidation resistance to 870 degrees Celsius intermittent service and good weldability without post-weld heat treatment in most applications. The 3.0mm diameter sits at the coarse end of typical welding wire range, suited to high-deposition manual metal arc or mechanised TIG root passes rather than fine-sheet MIG work.

304 grade welding wire offers general corrosion resistance suitable for food equipment, architectural frameworks, and chemical handling where exposure is mild to moderate. The austenitic structure provides toughness down to cryogenic temperatures, though 304 is not designed for sustained chloride exposure where pitting or stress corrosion cracking may initiate. For welding wire, surface cleanliness and copper coating (if present) significantly affect feedability and arc stability. The source does not specify whether this product carries a copper flash or other surface lubrication, which buyers should confirm for their feeding equipment compatibility.

Intended buyers include construction fabricators, automotive exhaust manufacturers, and general equipment builders requiring manual or semi-automatic stainless welding. The supplier notes suitability for both MIG and TIG processes, though 3.0mm is coarse for typical MIG applications below 200A. No minimum order quantity, price, or lead time is stated in the source material. Buyers should confirm packaging format (spool, coil, or straight length), protective gas requirements (typically Ar or Ar/CO2 mixtures), and whether the wire is classified under AWS A5.9 ER308 or ER308L specifications.

Wuqiang Huili Fiberglass Co., Ltd. is located in Haozhuang Industry Zone, Wuqiang County, Hengshui 053300, Hebei Province, China. The company name indicates historical or continuing involvement in fiberglass products, though this listing covers stainless steel welding wire, suggesting product line diversification or trading activity. The supplier holds a 'harbor' trust tier with zero recorded response rate and zero average response hours, indicating limited engagement data rather than verified active trading history. The Hebei location places the company in China's northern industrial belt, with access to steel production from Tangshan and Shijiazhuang mills.

No manufacturing facility details, employee count, revenue, client references, or certification scope is provided in the source material. The supplier description emphasises product application rather than company-specific quality systems or process controls. Buyers should verify whether Wuqiang Huili maintains wire drawing capability in-house or sources finished wire, as this affects technical support and batch consistency. The absence of stated ISO 9001, ISO 3834, or similar welding quality system certification should be noted and confirmed directly with the supplier if required for project specifications.
