Import Aisi Ba Mirror 318 Stainless Steel Flat Bar — Buy in wholesale FOB from Supplier in China

The Aisi Ba Mirror 318 stainless steel flat bar from Jiangsu Steel Group Co., Ltd. is a cold-finished austenitic stainless steel product with a bright annealed (BA) mirror surface, supplied from Shanghai with FOB or CIF terms available. Width spans 2 mm to 500 mm with custom lengths cut to buyer requirements, and the material conforms to ASTM A276 alongside AISI, GB/T 1220, and JIS G4303 standards. The 318 designation within the 300 series indicates a grade engineered for elevated chromium and nickel content, delivering markedly better corrosion resistance than standard 304 in chloride-bearing environments. Surface finish options extend beyond BA mirror to black, pickled, bright, and hairline, letting buyers match the bar to visible architectural elements or concealed structural roles.

Production draws on imported raw materials, with the mill citing ISO 9001:2008 quality system certification for its processes. The work-hardening rate of 318-grade austenitic stainless steel is notably higher than ferritic alternatives, meaning formed sections gain strength but require greater power during cold bending. Bright annealing after cold rolling preserves the mirror surface by preventing oxidation scale, eliminating the need for subsequent pickling or grinding on decorative faces. Typical chemical composition for 318-grade material runs 18-20% chromium, 13-15% nickel, and 3-4% molybdenum, though buyers should request a mill test certificate to confirm actual ladle analysis for each heat.

Primary applications span architectural cladding, handrails, kitchen equipment frames, and decorative trim where the BA mirror finish removes secondary polishing costs. Engineering structures, support brackets, and automotive trim components also draw on the flat bar's combination of corrosion resistance and clean aesthetics. The supplier notes 20-30 days shipment after down payment or irrevocable L/C sight, with payment by L/C at sight or T/T against copy of B/L. Buyers must specify material grade, surface finish requirement, and whether fixed lengths are needed when requesting quotations, as these variables directly affect costing.

Jiangsu Steel Group Co., Ltd. maintains its registered address at 10/F, No. 257 Siping Road, Shanghai 200080, in the Hongkou district, operating as an imported-tier supplier with a harbor trust designation. The profile shows a 0.00% response rate with zero average response hours, signalling that buyer outreach through the platform may go unanswered and direct follow-up by email or phone is advisable. No employee count, annual revenue, year of establishment, or client references appear in the available data, so claims about scale or market position cannot be substantiated. The listing presents itself as a steel trader or mill representative offering 200, 300, and 400 series stainless steel long products with multiple surface finishes.

The company's product scope centres on flat bars for architecture and engineering structures, with ASTM A276 compliance cited across the range. Verification signals are limited: the harbor trust tier indicates basic profile completion rather than third-party audit or on-site inspection. Buyers should treat ISO 9001:2008 certification as a historical quality system claim and request current certificate validity directly, as the standard was superseded by ISO 9001:2015. No information is provided about production capacity, in-house testing facilities, or whether Jiangsu Steel Group operates its own mill or acts as a trading intermediary.
