Import 310s Seamless Stainless Steel Pipe — Buy in Bulk from Supplier in China

Zhejiang Yingsheng Stainless Steel Pipe Co., Ltd. produces SUS 310S seamless stainless steel pipe with outer diameters from 6 mm to 630 mm and wall thicknesses from 1 mm to 45 mm, covering both instrumentation tubing and large-bore process piping requirements. The Wenzhou-based manufacturer references ASTM and JIS compliance, with seamless construction providing uniform circumferential strength for high-pressure thermal and chemical service. This dimensional range exceeds many regional competitors, permitting single-source procurement for mixed-diameter projects in power generation and chemical processing.

SUS 310S corresponds to UNS S31008, with the same 24-26% chromium and 19-22% nickel specification as AISI 310S, ensuring oxidation resistance to 1150°C and comparable creep rupture properties. The broad wall thickness programme, from light-wall 1 mm up to heavy 45 mm, indicates access to multiple production routes: cold-drawn and cold-rolled for precision dimensions, and hot-rolled or extruded for thicker sections. JIS G3459 compliance, referenced alongside ASTM, suggests production for both domestic Japanese market requirements and broader Asian project specifications.

Application sectors cited include oil and gas, chemical processing, and food processing, though buyers should note that 310S is rarely required for food contact given cost premiums over 304/316 grades. Custom lengths and finishes are offered, which for 310S typically means pickling, bright annealing, or polished surfaces for architectural or clean-service installations. Trade terms including FOB and CIF are mentioned, with L/C and T/T payment methods accepted, though all commercial conditions require direct confirmation given the imported supplier tier and zero published response metrics.

Zhejiang Yingsheng Stainless Steel Pipe Co., Ltd. is located in Lantian Industrial Zone, Haibin, Longwa, Wenzhou 325024, China, within one of the country's most concentrated stainless steel pipe and fitting production clusters. The supplier carries an imported tier classification with harbor trust tier, indicating data ingestion from an third-party source rather than direct platform registration. Buyers should treat published capabilities as provisional until verified through direct technical correspondence and, where possible, factory audit or video inspection.

The Wenzhou location provides proximity to Ningbo-Zhoushan Port, China's largest throughput port, with obvious logistics advantages for containerised pipe export. However, the zero response rate and zero average response hours mean that initial enquiry handling, technical clarification, and quotation turnaround cannot be assumed. The company profile does not disclose founding date, production capacity, number of rolling mills, or major reference projects, so buyers must independently assess manufacturing credentials through ISO 9001 certificate verification and sample qualification testing.
