Import 304 316l 431 Stainless Steel Wire — Buy in wholesale FOB from Supplier in China

Jiangsu Steel Group Co., Ltd. produces stainless steel wire in three distinct alloy grades, 304, 316L and 431, with diameters spanning 0.02 mm to 2.5 mm to serve diverse industrial forming and fastening applications. The austenitic grades 304 and 316L offer excellent corrosion resistance and cold heading formability, while the martensitic 431 grade provides higher strength and moderate corrosion resistance through heat treatment. All grades are produced to AISI, ASTM, DIN, GB and JIS standards, with surface finishes including electrolysis bright, bright and matt conditions to suit downstream processing requirements.

The wire is supplied in soft, semi-soft and hard drawn conditions, with the latter achieving tensile strengths suitable for spring manufacture and cold-formed fasteners. Diameter range from 0.02 mm to 2.5 mm covers fine mesh weaving, welding electrode cores, precision springs, and heavy gauge construction ties. Standard packaging includes nylon bags, woven bags and coils on wooden spools, with custom options available. The 316L grade's reduced carbon and molybdenum addition suits marine and chemical exposure, while 431's chromium content and hardenability target wear-resistant components and aerospace fasteners.

Application sectors include bicycle component manufacturing, kitchen and sanitary ware, retail display shelving, pet enclosure mesh, aquaculture gill racks, decorative baskets, and medical instrument access parts. The supplier's Shanghai location provides port access for FOB, CFR and CIF shipments with quoted 10 working day lead times post-deposit. Buyers should verify current availability, exact diameter tolerances for their specification, and whether mill test certificates and third-party inspection arrangements remain standard offerings, as these operational details require direct confirmation with Jiangsu Steel Group.

Jiangsu Steel Group Co., Ltd. maintains a registered address at 10/F, No.257 Siping Road, Shanghai 200080, in the Hongkou district, positioning the company within China's primary commercial and shipping hub rather than necessarily at a production mill. The supplier holds both Imported and Harbor trust tiers on the platform, with a zero percent response rate and zero average response hours indicating no tracked engagement through this channel. This profile structure suggests a trading company or group sales office model rather than direct mill manufacturing, though the extent of vertical integration is not specified in available data.

The company's product specialisation centres on stainless steel long products, specifically wire in multiple grades and conditions, with stated loading from Shanghai port and standard delivery terms of FOB, CFR and CIF. No manufacturing facility details, production capacity figures, employee count, annual revenue, ISO certification status, or named client references appear in the listing. Buyers should conduct due diligence to distinguish whether Jiangsu Steel Group operates its own melting and wire drawing assets or sources through mill partnerships, as this distinction affects quality consistency, certification chain of custody, and negotiating leverage on custom specifications and volume pricing.
