304 304L 316 316L Seamless Stainless Steel Pipe
Hongguan Steel Group Co. Ltd. supplies seamless stainless steel pipe across four austenitic grades: 304, 304L, 316 and 316L, with wall thicknesses for seamless tube spanning 1.2 mm to 50 mm and welded variants from 0.2 mm to 12 mm. The pipes conform to ASTM A312 and A213 standards, with additional compliance to JIS, AISI, GB, DIN and EN norms, and are offered in hot-rolled and cold-rolled forms with surface finishes including polished, pickled, hairline and mirror. Standard length is 6 metres, though custom lengths are available on request.
Grade 304 provides general corrosion resistance suitable for kitchen supplies, industrial manufacturing and building decoration, while 304L's lower carbon content improves weldability in chemical equipment and storage tanks. Grade 316 adds molybdenum for enhanced resistance to chlorides and marine environments, and 316L combines this with reduced carbon for welded structures in aerospace processing and gas transportation. The supplier notes applications spanning household appliance housings through to aerospace components, indicating breadth across pressure and non-pressure service.
Buyers in petrochemical, food processing and marine sectors typically procure these pipes for fluid transport, heat exchangers and structural supports where ASTM A312/A213 compliance is mandatory. The material certificates, heat treatment records and third-party inspection reports should be requested at quotation stage. Surface finish selection (polished for hygiene, pickled for weld prep, mirror for architectural use) should align with end-use requirements.
| Steel Grades | 304, 304L, 316, 316L (AISI designation) |
| Seamless Wall Thickness Range | 1.2 mm - 50 mm |
| Welded Wall Thickness Range | 0.2 mm - 12 mm |
| Applicable Standards | ASTM A312, ASTM A213, JIS, AISI, GB, DIN, EN |
| Manufacturing Methods | Hot rolled and cold rolled |
| Surface Finishes | Polished, pickled, hairline, mirror |
| Standard Length | 6 metres (custom lengths available) |
| Typical Seamless OD Tolerance | ASTM A312 standard: +/- 0.5 mm typical for diameters under 48.3 mm |
| Typical Pickling Passivation | Nitric/hydrofluoric acid treatment standard for weld corrosion resistance |
| Typical Packaging | Standard export seaworthy package, plastic end caps, wooden crates or steel frames |
Hongguan Steel Group Co. Ltd. is located at 102-b5 Supporting Office Area of Customs Supervision Warehouse in the Comprehensive Bonded Zone, No. 5999 Aerospace Avenue, High Tech Zone, Jinan, Shandong Province, China. The supplier holds a harbor trust tier, which indicates a foundational verification level on the platform. The response rate is recorded at 0.00% with an average response time of zero hours, meaning buyers should expect to initiate contact and may need to follow up actively to secure quotations or technical clarifications.
The company lists stainless steel pipe and tube across 200, 300 and 400 series grades, with the immediate offering focused on 304/304L/316/316L seamless pipe. No manufacturing history, year of establishment, headcount, revenue figures or named clientele are stated in the available profile. Buyers should verify the supplier's mill origin, whether pipes are produced in-house or sourced from partnered mills, and request mill test certificates (MTC) with chemical composition and mechanical property data before placing trial orders.
Seamless stainless steel pipes in grades 304, 304L, 316, and 316L are widely used in chemical, petrochemical, food processing, and marine applications where corrosion resistance and durability are critical. These pipes are manufactured to ASTM A312/A213 standards with options for hot-rolled and cold-rolled finishes including polished, pickled, and mirror surfaces. Ideal for global B2B procurement, they meet international quality standards and are available in various sizes for industrial piping systems.

Sourcing 304 304L 316 316L Seamless Stainless Steel Pipe from Hongguan Steel Group Co. Ltd. - China Import Guide
Before ordering from Hongguan Steel Group Co. Ltd., verify that the mill test certificates include full chemical composition (including Cr, Ni, Mo, Mn, N for the grade ordered), mechanical test results (yield strength, tensile strength, elongation), and heat treatment condition (solution annealing temperature and quench method). Request a sample certificate for a recent heat to assess documentation quality. Confirm the supplier's quality management system registration, and whether they hold ISO 9001 or a mill-specific certification such as PED 2014/68/EU or ASME for pressure equipment. Validate that the stated ASTM A312/A213 compliance is backed by third-party inspection if required for your project.
Logistics from Jinan, Shandong Province, typically utilise Qingdao or Tianjin port for ocean freight. Incoterms are not stated and must be negotiated; EXW, FOB Qingdao/Tianjin, or CIF terms are common for Chinese pipe exports. Lead time is described as 'prompt delivery or as the order quantity', which requires clarification, whether this means ex-stock for standard sizes or mill rolling for larger quantities. Payment terms should be confirmed, letter of credit or Telegraphic Transfer with deposit are standard practice. The Comprehensive Bonded Zone location may offer customs facilitation, but buyers should confirm if this confers any tax or duty advantage for their specific shipment routing.
On receipt, inspect pipe markings for heat number, grade, specification and mill identification; these should match the mill test certificate. Measure wall thickness and diameter at multiple points to verify within ASTM A312 tolerance bands, particularly at pipe ends where handling damage occurs. Surface finish should be checked against the ordered specification (polished, pickled, mirror or hairline). For critical applications, engage an independent third-party inspector to witness tests at the mill or inspect at destination. Documentation required typically includes commercial invoice, packing list, bill of lading, certificate of origin, mill test certificates, and any inspection release notes. Ensure all certificates are original and traceable to the heat numbers supplied.
