Import 304l Bright Soft Annealed Stainless Steel Wire — Buy in wholesale FOB from Supplier in China

Jiangsu Steel Group Co., Ltd. supplies 304L Bright Soft Annealed Stainless Steel Wire, an austenitic grade wire produced from UNS S30403 with nominal composition 18 percent chromium and 8 percent nickel plus controlled low carbon. The bright annealing process subjects the wire to heat treatment above recrystallisation temperature under controlled atmosphere, yielding a smooth, oxide-free surface finish alongside high ductility and reduced hardness compared with cold-drawn alternatives. Available diameters span from 0.08 mm up to 12 mm, with plastic spool packing for fine gauges (DIN125 through DIN250, net weights 2 kg to 15 kg per spool) and coil packing for heavier gauges (inner diameters 400 mm, 500 mm, 600 mm or 650 mm, coil weights 30 kg to 80 kg).

The 304L grade's carbon content is deliberately restricted below 0.03 percent to mitigate chromium carbide precipitation and intergranular corrosion in welded or sensitised conditions. Bright soft annealing refines the microstructure to a homogeneous austenitic phase, improving cold heading, bending and forming characteristics without requiring additional intermediate annealing. Surface finish is characterised by a reflective, scale-free appearance that reduces contamination risk in downstream processes. Typical mechanical properties in the annealed condition include tensile strength around 515 MPa and elongation exceeding 40 percent, though buyers should request mill test certificates for the specific heat supplied.

This wire serves manufacturers of woven mesh, hose reinforcement, filtration screens, wire rope and steel strand for architectural and industrial cable systems. Spring makers and cold-forming operations value its consistent tensile properties and reliable feed behaviour in automated coilers. Kitchenware producers use it for burner frames and cooking utensil components where corrosion resistance and cleanability matter. Importers should verify that Jiangsu Steel Group Co., Ltd. provides mill test certificates conforming to EN 10204 3.1 or equivalent, and confirm packing specifications suited to their handling equipment and container loading plans.

Jiangsu Steel Group Co., Ltd. maintains its registered address at 10/F, No. 257 Siping Road, Shanghai 200080, Hongkou, China, operating within the imported supplier tier on this marketplace with a harbour trust designation. The listing presents no response rate data, average response time, or verification of production facility ownership, so buyers should treat this profile as an unverified trading entity until directly confirmed. No disclosed certifications, registered capital, year of establishment, or factory audit documentation appear in the available profile.

The company offers 304L Bright Soft Annealed Stainless Steel Wire across a broad diameter range with detailed packing specifications, suggesting commodity trading experience in stainless steel long products. The product description references mill test certificates for quality assurance, but the listing does not confirm whether these are EN 10204 3.1, 3.2, or third-party inspection reports. Buyers are advised to request supplier qualification documents, including ISO 9001 certification scope and material origin mill references, before committing to trial orders.
