ASTM A312 TP304L stainless steel pipe from Wenzhou Chenhui Steel Co., Ltd is a low-carbon austenitic grade containing 18% chromium and 8% nickel with carbon limited to 0.035%. The seamless and welded variants are engineered for high-pressure and corrosive environments, with outer diameters ranging from 6 mm to 762 mm, wall thicknesses from 0.9 mm to 60 mm, and lengths from 4,000 mm to 13,000 mm. This specification is designed to resist intergranular corrosion, making it suitable for chemical processing, petroleum, and food industry applications.
The material’s low carbon content improves weldability and reduces sensitisation during welding, while its austenitic structure provides excellent formability and toughness at cryogenic temperatures. Typical industry standards for TP304L include a tensile strength of 515 MPa minimum and yield strength of 205 MPa minimum, with elongation at break around 35%. Surface finishes are usually pickled and passivated to enhance corrosion resistance, and the pipes are supplied in standard bundles or crates for export.
This grade is commonly sourced by buyers in oil and gas, pharmaceutical, and water treatment sectors where resistance to oxidising acids and chlorides is critical. Wenzhou Chenhui Steel Co., Ltd offers direct-reading spectrometer and eddy current flaw detection for quality assurance, with PMI, IGC, and metallurgical testing available on request. The factory’s annual output includes 10,000 tons of seamless pipes and 20,000 tons of welded pipes, supporting bulk orders for global B2B buyers.

Before ordering ASTM A312 TP304L pipes from Wenzhou Chenhui Steel Co., Ltd, verify the exact grade, dimensions, and surface finish to ensure compliance with your project specifications. Request mill test certificates (MTCs) to confirm chemical composition and mechanical properties, as these documents are critical for quality assurance in industrial applications.
Confirm logistics details such as port of loading, Incoterms (e.g., FOB, CIF, CFR), and lead times, which can vary based on order size and production schedules. The supplier’s location in Zhejiang Province means shipments typically depart from Chinese ports like Ningbo or Shanghai, so factor in transit times and shipping costs for your region.
For quality checks, insist on third-party inspection or pre-shipment testing to validate dimensions, surface finish, and material integrity. Request evidence of pickling and passivation processes, and ensure all documentation, including packing lists and certificates of origin, is complete and accurate to avoid delays during customs clearance.
