从China供应商批发进口304h Stainless Steel Flat Bar — FOB条款

Jiangsu Steel Group Co., Ltd. offers 304h Stainless Steel Flat Bar in thicknesses from 2mm to 100mm and widths from 10mm to 500mm, with standard lengths of 2-6 metres or customised cutting to client requirements. The 304h designation indicates a higher-carbon austenitic variant (0.04-0.10% C) of standard 304, providing improved elevated-temperature strength for boiler, heat exchanger, and pressure equipment applications. Surface treatments available include pickling, bright finish, or black scale, with packaging in bundles using seaworthy wooden pallets. The supplier confirms ISO9001 certification and provides material reports plus mechanical performance reports with shipment.

Flat bars in 304h grade deliver the characteristic chromium-nickel austenitic corrosion resistance with carbon content optimised for creep resistance above 425 degrees Celsius where 304L would soften. The broad dimensional range, from slender 2mm by 10mm sections up to heavy 100mm by 500mm plate-like bars, covers applications from machinery keys and shafts through to structural bracing and chemical vessel stiffeners. Bright-finished bars suit decorative or precision-machined components where surface integrity affects fatigue performance; pickled bars suit welded fabrication; black-scale embedded-scale finish suits subsequent hot-working or heavy machining. Standard grades in the supplier's range include 304, 304L, 309S, 310S, 316L, 316Ti, 317L, 321, 347H, 409, 409L, 410, 420, and 430, enabling alloy substitution for specific corrosion or temperature requirements.

Key buyer segments include shipbuilders, petrochemical constructors, power generation equipment fabricators, food processing machinery manufacturers, and medical device producers. The flat bar serves in boiler and heat exchanger construction, machinery hardware, structural frames, and decorative architectural elements. Loading is available from Chinese ports with FOB or CIF terms, delivery in 5-30 days after prepayment confirmation, and payment by standard trade instruments. The ISO9001 certification covers quality management, though scope details and audit expiry should be confirmed directly with the supplier.

Jiangsu Steel Group Co., Ltd. operates from its registered address at 10/f No.257 Siping Road, Shanghai 200080, Hongkou, China, with Shanghai serving as its commercial and logistics hub despite the Jiangsu naming. The supplier profile shows imported-tier classification and harbour trust-tier status. Response metrics display 0.00% response rate with zero average hours, so buyers cannot rely on platform-mediated communication history and must establish direct contact.

The flat bar listing extends the supplier's stainless long-products portfolio, which includes grades from 304 through 430 and specialised heat-resistant alloys such as 310S, 316Ti, and 347H. ISO9001 certification is claimed, supported by material and mechanical performance reports per shipment. The profile does not disclose manufacturing location, furnace or rolling mill specifications, annual tonnage, employee numbers, or named reference customers. Buyers should treat unverified claims cautiously and conduct due diligence accordingly.
