Import 310s/310h Stainless Steel Sheet — Buy in wholesale FOB from Supplier in China

310S/310H stainless steel sheet is an austenitic heat-resisting grade designed for sustained operation in oxidising environments up to 1150 degrees Celsius, with 310H (UNS S31009) offering higher carbon content for elevated-temperature creep resistance and 310S (UNS S31008) providing improved weldability and reduced sensitisation in moist corrosive conditions below the high-temperature threshold. The alloy contains 25 percent chromium and 20 percent nickel with controlled carbon, giving it exceptional oxidation resistance and the ability to withstand thermal cycling in furnace components and petrochemical equipment. Puxin Stainless Steel Co., Ltd. lists this material for B2B buyers sourcing industrial-grade sheet for thermal and chemical processing applications, with standard dimensions available and flexible minimum order quantities for international trade.

The chromium content forms a self-healing oxide scale that protects against carburisation and nitriding in reducing sulphur-free atmospheres, while the high nickel level maintains austenitic stability across the full operating range. Typical mill finish is hot-rolled annealed and pickled (HRAP) or cold-rolled 2B, with thicknesses commonly ranging from 3.0 mm to 50.0 mm and widths from 1000 mm to 2000 mm depending on mill capability and order specification. Surface finishes may include No. 1 (hot-rolled, annealed, pickled), 2B (cold-rolled, annealed, pickled, skin-passed), or specialised finishes for cladding applications. Standard plate thickness tolerance follows ASTM A480/A480M, with closer tolerances available on request for precision fabrication. Intergranular corrosion resistance of 310S is superior to standard 310 in the 650-900 degrees Celsius sensitisation range owing to its lower carbon content.

Primary applications include furnace tubes, burner shields, heat treatment baskets and fixtures, radiant tubes, cement kiln components, and petrochemical reformer tubes where extended service life at temperature outweighs the premium over standard 304/316 grades. Buyers in power generation, cement production, and oil refining typically specify 310H for creep-limited design life at temperatures above 1000 degrees Celsius, while 310S serves heat exchangers and process vessels in moderate-temperature corrosive service. When sourcing from Puxin Stainless Steel Co., Ltd., confirm the exact grade required (310S or 310H), required thickness and width, surface finish, and whether third-party inspection or mill test certificates to EN 10204 3.1 are included. Also verify packing method, typically steel strapping on wooden pallets with moisture-resistant wrapping for ocean freight, and clarify Incoterms and payment structure before finalising orders.

Puxin Stainless Steel Co., Ltd. is located at R1007, No.287 Guangyi Road, Liangxi District, Wuxi, Jiangsu Province, China, placing it within the Wuxi stainless steel distribution cluster, one of China's major centres for stainless steel processing and trade. The company holds a 'harbor' trust tier on the platform, with a response rate of 0.00 percent and average response hours of zero, indicating that prospective buyers should not rely on rapid quotation turnaround and should plan communications accordingly. The listing presents Puxin as a manufacturer, exporter, and supplier of SS 309/310/310S plates and sheets, with this specific offering targeting B2B buyers in thermal equipment, furnace construction, and petrochemical processing sectors. No verified factory audit, ISO certification, or production capacity figures are stated in the source data, so buyers should request direct evidence of quality management systems and manufacturing capability before committing to large orders.

The supplier's product description emphasises high-temperature properties, weldability, and adaptability for 310 grade, with specific differentiation between 310H for high-temperature applications and 310S for moist corrosive environments below the high-temperature threshold. Puxin does not disclose headcount, annual revenue, major client references, or years in business in the provided profile, so these cannot be verified independently. Buyers are advised to conduct due diligence on the company's actual production assets, whether it operates melting, hot rolling, and cold rolling facilities or functions primarily as a trading and processing company. Requesting mill test certificates, sample material for independent chemical analysis, and references from existing customers in comparable industries would be prudent steps before establishing a supply relationship.
