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

Jiangsu Steel Group Co., Ltd. offers 304 bright soft annealed stainless steel wire, an austenitic grade containing 18% chromium and 8% nickel that undergoes bright annealing to achieve a smooth, oxide-free surface with enhanced ductility. The wire is supplied in diameters from 0.08 mm to 12 mm, with finer diameters (0.08-0.7 mm) spooled on DIN-standard plastic drums and heavier gauges (0.60-12 mm) supplied in coils of 30-80 kg with inner diameters of 400-650 mm. The bright annealing process heats material above its recrystallisation temperature before controlled cooling, refining grain structure and eliminating work-hardening effects from prior cold drawing. This product targets precision applications including woven mesh, filtration equipment, hose reinforcement, kitchen ware frames, wire ropes, steel strand, and springs where surface integrity and uniform mechanical properties are critical. The 304 grade provides adequate corrosion resistance for indoor and mild atmospheric environments, though chloride exposure requires consideration of molybdenum-enhanced alternatives. Typical tensile strength in the annealed condition ranges 500-700 MPa, with elongation exceeding 40% in standard test configurations, though buyers should request mill certificates for batch-specific mechanical test results.

The material conforms to AISI 304 / UNS S30400 chemistry limits, with carbon typically at 0.08% maximum and nickel content ensuring stable austenitic structure across fabrication temperatures. Bright annealing distinguishes this wire from conventionally annealed product by eliminating surface oxide scale, reducing subsequent cleaning requirements and improving aesthetic appearance in visible applications. The soft annealed condition permits tight-radius bending and complex forming without cracking, a property valued in mesh weaving and spring coiling operations. Surface finish correlates directly with die wear during final drawing passes and the protective atmosphere composition during annealing, typically hydrogen-nitrogen mixtures. Buyers should verify that supplied wire meets their required dimensional tolerances, as precision applications demand consistency in ovality and diameter deviation. The DIN spool specifications (125, 160, 200, 250) refer to flange diameters, with net weights per spool ranging 2 kg to 15 kg depending on wire diameter and packing density. Coil weights of 30-80 kg suit continuous-feed industrial equipment, with inner diameters selected to match customer dereelers.

Primary applications span industrial filtration (particle retention screens, liquid/solid separation), architectural mesh (facade cladding, decorative screens), food processing equipment (conveyor belts, spray nozzles), and precision mechanical components (compression springs, tension springs, cable assemblies). The wire's clean surface and controlled mechanical properties make it suitable for welding by TIG or resistance methods, though post-weld sensitisation should be assessed for corrosive service. Importers typically source this product under CFR or CIF terms from Shanghai or nearby ports, with lead time and minimum order quantity requiring direct confirmation with Jiangsu Steel Group Co., Ltd. given the zero response rate indicated in current profile data. The supplier's imported tier and harbor trust designation suggest established export capability, though buyers should conduct independent verification of quality management systems and request material test certificates with chemical composition and mechanical property data. Packaging in moisture-resistant film with desiccant is standard for ocean freight to prevent transit corrosion.

Jiangsu Steel Group Co., Ltd. maintains its registered office at 10/F, No. 257 Siping Road, Hongkou District, Shanghai 200080, China, with production and export operations centred in China's eastern manufacturing corridor. The supplier holds an imported tier designation within marketplace classification, indicating external sourcing or mixed supply chain structure rather than vertically integrated mill production. Current profile indicators show a harbor trust level with zero percent response rate and no recorded average response hours, which prospective buyers should factor into communication planning and due diligence timelines. The company lists stainless steel wire and related products across multiple specification configurations, suggesting catalogue breadth rather than single-product specialisation.

The supplier's custom specification references international standards and competitive positioning for global trade, though no specific certifications, factory audits, or third-party verifications are stated in the available profile data. Buyers should independently confirm Jiangsu Steel Group Co., Ltd.'s quality management certification status (ISO 9001, ISO 14001 typical for Chinese steel exporters), material traceability systems, and capability to provide mill test certificates with chemical and mechanical data. The address in Shanghai's commercial district rather than an industrial zone may indicate trading office function; clarification of manufacturing location and direct factory relationship is advisable before contract commitment. Given response rate indicators, multiple contact channels and documented follow-up are recommended to secure quotations and technical confirmations.
