Import 330 Stainless Steel Bar — Buy in wholesale FOB from Supplier in China

Jiangsu Steel Group Co., Ltd. supplies 330 stainless steel bar in round, square, flat, hexagon, channel, threaded and angle profiles, with outer diameters from 1.0 mm to 400 mm and standard mill lengths of 3000 mm or 6000 mm against customer specification. The material is an austenitic chromium-nickel iron-based alloy designated UNS N08330, recognised for sustained performance in oxidising environments above 1000 °C where conventional 300-series grades fail. Surface finishes span bright, pickled and black, with form options covering hot-rolled black, acid-pickled, cold-drawn bright and polished conditions.

The alloy's 35 % nickel and 19 % chromium nominal composition (typical for 330 grade) provides resistance to thermal cycling and carburising atmospheres, making it standard in furnace retorts, heat-treatment fixtures and petrochemical reformer tubing. Bar forms are produced by forging, hot rolling, cold drawing or peeling, depending on dimensional and surface requirements. Diameter tolerance H9 is achievable on precision-ground product, with straightness and corner radii conforming to DIN 17440 / 17220 and BS 970 Part 4 where applicable. The supplier lists ISO 9001 certification for quality management.

End-use sectors include petroleum refining, chemical processing, power-generation construction, textile machinery, aerospace structural hardware and metallurgical equipment. Buyers typically specify 330 bar when stress-rupture strength at 870 °C and resistance to sigma-phase embrittlement are required. Import considerations include confirming the exact nickel and chromium assay against ASTM B511 or equivalent, verifying mill-test certificates for elevated-temperature tensile data, and agreeing on packaging suitable for ocean freight from Shanghai port. Response-rate data for this supplier is currently unavailable, so buyers should establish direct contact to confirm lead time, minimum order quantities and current capacity allocation.

Jiangsu Steel Group Co., Ltd. maintains a registered address at 10/F, No. 257 Siping Road, Shanghai 200080, Hongkou District, China, situating its commercial operations within China's primary steel-trading hub. The supplier is classified under an imported tier with a harbour trust designation, indicating platform-registered status without third-party verification depth. Both response rate and average response hours show as zero in available data, so buyers should treat initial outreach as unverified and confirm responsiveness directly before relying on quoted timelines.

The listing presents a broad dimensional and form portfolio for 330 stainless steel bar, from 1 mm precision wire to 400 mm heavy round and structural sections, suggesting mill-direct or large-stockholder capability rather than trader-only operations. No workforce count, annual revenue, founding year, named client references or specific production-capacity figures appear in the source profile, so claims about scale or market position cannot be substantiated. Buyers are advised to request a current mill-test certificate, audit the ISO 9001 scope for bar-product coverage, and verify that the Shanghai office coordinates with a Jiangsu-based mill or warehouse before placing trial orders.
