Import 304 Cu Stainless Steel Wire — Buy in wholesale FOB from Supplier in China

304Cu stainless steel wire from Jiangsu Steel Group Co., Ltd. is an austenitic chromium-nickel grade with copper addition, supplied in diameters from 0.018 mm to 20 mm in soft, semi-soft, or hard-drawn condition. The copper content enhances cold heading and forming performance compared to standard 304, reducing work hardening rates during deformation processes. This wire meets AISI, ASTM, DIN, GB, JIS, and SUS standards, with surface finishes including electrolysis bright, bright, or matt. The supplier offers Shanghai Port loading with delivery terms spanning FOB through DDP, and indicates a 10-working-day lead time after deposit receipt with mill test certificate provision.

The 304Cu variant typically contains 8.5-9.5% nickel, 18-19% chromium, and copper in the 1.5-3.0% range depending on producer formulation, though buyers should verify exact composition on the mill test certificate. Copper addition improves drawability and reduces galling during cold heading of fasteners and screws, making 304Cu preferred over 304 for intricate formed components. Wire condition (soft, semi-soft, hard) determines tensile strength and suitability: soft annealed wire offers maximum ductility for severe forming, while hard-drawn wire provides higher strength for spring or structural applications. The 0.018 mm minimum diameter represents ultra-fine capability suitable for mesh weaving and medical textile applications, while 20 mm covers heavy structural and welding wire requirements.

Primary applications span welding electrode core wire, woven mesh production, fasteners and cold-headed components, bicycle fittings, kitchen and sanitary hardware, pet cages, gill racks, decorative handles, baskets, and medical and food machinery access parts. The supplier's broad grade range from 201 through 2205 suggests trading or multi-mill sourcing rather than single-line specialisation. Packaging options include nylon bag, woven bag, or coil formats with client-specific alternatives available. Buyers should confirm coil weight, inner diameter, and layer winding pattern to match their de-coiling and straightening equipment.

Jiangsu Steel Group Co., Ltd. is headquartered at 10/f No.257 Siping Road, Shanghai 200080, Hongkou district, with export operations through Shanghai Port. The supplier is classified as imported-tier with harbor trust status, indicating baseline platform presence without advanced verification. Response metrics show 0.00% response rate and zero recorded average response hours, which may reflect inactive enquiry management rather than operational incapacity. The listing presents an extensive grade portfolio from 201 through duplex 2205 and numerous welding wire grades, suggesting either substantial scale or trading-oriented business model without mill exclusivity.

The supplier's product application description cites bicycle fittings, kitchen and sanitation tools, goods shelving, pet cages, gill racks, decorative handles, baskets, and food and medical machinery components, indicating broad market coverage rather than sector specialisation. No ISO certification, manufacturing licence, or export registration details appear in the profile. The chemical composition table provided covers multiple grades but should be cross-checked against mill test certificates for actual heat analysis. Buyers should conduct due diligence on the supplier's quality assurance capability, particularly for diameter tolerances on fine wire below 0.5 mm where drawing die maintenance and online laser gauging become critical.
