Import Astm A213 Tp321h Stainless Steel Pipe — Buy in wholesale FOB from Supplier in China

ASTM A213 TP321H is a titanium-stabilised austenitic stainless steel seamless pipe, designated UNS S32109 with nominal composition 18Cr-12Ni-Ti. Huanan Special Steel Co., Ltd. lists this grade for boiler and heat exchanger service, with available diameters from 6mm to 580mm and wall thickness from 1mm to 30mm. Length options span 4000mm to 15000mm depending on forming method and order requirements. The supplier notes cold drawing, cold rolling, hot rolling, and heat expansion as delivery conditions. This grade offers superior creep resistance compared to standard TP321, making it suitable for sustained operation above 800°F (427°C).

TP321H achieves its stabilised structure through controlled titanium additions that form titanium carbides preferentially to chromium carbides, thereby preventing sensitisation and intergranular corrosion in the heat-affected zone after welding or prolonged high-temperature exposure. The H suffix denotes higher carbon content (0.04-0.10% typical) than standard TP321, which confers improved elevated-temperature strength. ASTM A213 specifies this grade for seamless ferritic and austenitic alloy-steel boiler, superheater, and heat-exchanger tubes. Standard industry practice requires solution annealing after forming to restore corrosion resistance and mechanical properties. Typical hardness ranges from 85 HRB maximum in the solution-annealed condition, with tensile strength of 75 ksi minimum and yield strength of 30 ksi minimum at room temperature per ASTM A213.

Buyers for this product include petrochemical refineries, fossil and nuclear power plants, chemical process licensors, and EPC contractors for energy infrastructure. Common applications include superheater tubes, reheater tubes, heat exchanger bundles, and furnace coil piping where thermal cycling and long-term creep strength are critical. The supplier offers trade terms FOB, CFR, or CIF from Chinese ports, with payment by TT or letter of credit. Lead time is stated as 15-20 days, though buyers should confirm current scheduling and mill availability for specific dimensions. EN 10204-3.1 material test certificates are available. Given the response rate of 0.00% shown, buyers should verify communication channels and current operational status before relying on quoted timelines.

Huanan Special Steel Co., Ltd. is located at Room 503, 28 Liyuan Building, Jiaxing, Zhejiang Province, 314000, China. The supplier carries an imported tier classification and a harbor trust tier designation. The response rate shown is 0.00% with zero average response hours recorded, which indicates no platform-tracked response history. Buyers should therefore initiate direct contact through available channels to assess responsiveness and confirm current trading status. The company's listed specialisations extend beyond stainless steel pipe to include super thick steel plate for offshore platforms and heavy industries, 9Ni alloy steel plate for LNG tank applications, and HIC/NACE-compliant steel plate for oil and gas and refinery sectors.

The supplier's product portfolio covers multiple austenitic grades including TP201, TP202, TP304, TP304L, TP304H, TP321, TP316, TP316L, TP317L, TP309S, TP310S, and TP347H. This breadth suggests mill or major stockist relationships, though no specific mill partnerships are named. The company's address in Jiaxing, a city within China's Yangtze River Delta manufacturing corridor, places it in proximity to major steel-producing regions and port infrastructure. No information is provided about year of establishment, number of employees, annual revenue, named clients, or factory ownership. Buyers should request company registration documents, ISO certification, and references for comparable supply contracts.
