Product Range and Specialties of Shangdun Special Materials Co.Ltd.

The catalogue covers seamless and welded stainless steel pipes (304, 304L, 316, 316L EP), duplex grades (UNS S31803, S2205), super‑duplex S32750, and super‑austenitic 253MA. Nickel‑based families include UNS N12160, N06007 (Hastelloy G), N06603 (Inconel 617), N06230 (Inconel 230), N08221, N08320, N08330 and alloy 801, each typically supplied to ASTM A213 or ASME SA‑213 specifications. Typical pressure ratings range from 150 bar for standard 304/316 pipe to 600 bar for ultra‑high‑pressure 316L tube; dimensions are commonly offered from 6 mm to 508 mm nominal diameter with wall thicknesses up to 30 mm. Buyers often request material test reports that reference standards such as EN 10217‑1, ASTM A240, and ISO 15156 for corrosion‑resistant alloys.

Trade and Export Information - Shangdun Special Materials Co.Ltd.

China is among the world’s largest exporters of stainless steel pipe and nickel alloy components. Major import markets include the Middle East (oil & gas), Europe (chemical processing), Southeast Asia (machinery) and North America (aerospace). HS 7304 and 7307 products are subject to customs duties that vary by destination, while nickel alloys under HS 7504‑7506 may attract anti‑dumping duties in certain jurisdictions. Typical buyer requirements include ISO 9001 quality‑management certification, CE marking for EU shipments, and compliance with the PED (Pressure Equipment Directive) for high‑pressure tubing. Export shipments are usually packed in wooden crates on pallets, loaded into 20‑ft or 40‑ft containers, and quoted on FOB or CIF terms. Chinese export licences for nickel alloys are governed by the Ministry of Commerce, and end‑users often need to provide end‑use declarations for strategic materials.

Sourcing from Shangdun Special Materials Co.Ltd. - Buyer Guidance

When sourcing from Shangdun, request a Mill Test Report (MTR) that lists chemical composition, tensile strength, yield strength and elongation in accordance with the applicable ASTM or EN standard. Verify that the product’s pressure rating, dimensions and surface finish match project specifications, and ask for a third‑party inspection certificate (e.g., SGS, Bureau Veritas) if required by the buyer’s jurisdiction. For nickel‑based alloys, buyers commonly request additional corrosion‑resistance test data such as ASTM B466 or ISO 15156‑2. Confirm the HS code used for customs clearance and ensure that any required certifications (ISO 9001, CE, PED) are provided before finalizing the order.

What stainless steel pipe grades are listed in the supplier’s catalogue?

The catalogue includes standard 304/304L, 316/316L (EP grade), duplex grades UNS S31803 (ASTM F51) and S2205, super‑duplex S32750 (HS 7304.41) and super‑austenitic 253MA (HS 7307.21).

Which nickel‑based alloys does Shangdun offer for high‑temperature applications?

Products include UNS N06007 (Hastelloy G), UNS N06230 (Inconel 230), UNS N06603 (Inconel 617), UNS N10665 (Hastelloy B‑2) and UNS N08801 (Incoloy 801), each referenced with the appropriate HS code (e.g., 7504.00 for Inconel 617).

Are the pipe dimensions and pressure ratings specified in the catalogue?

Typical dimensions range from 6 mm to 508 mm nominal diameter with wall thicknesses up to 30 mm. Pressure ratings commonly cover 150 bar for standard 304/316 pipe and up to 600 bar for ultra‑high‑pressure 316L tube, in line with ASTM A312 and EN 10217 standards.

What HS codes apply to the supplier’s stainless steel and nickel alloy products?

Stainless steel pipes and tubes use HS 7304 (e.g., 7304.11, 7304.41) and HS 7307 for bars. Nickel alloys are classified under HS 7504 (e.g., 7504.00 for Inconel 617), HS 7506 (e.g., 7506.20 for Hastelloy G‑35) and HS 7505 for nickel‑iron‑chromium alloys.

Which certifications should a buyer request from this supplier?

Buyers should request ISO 9001 quality‑management certification, a Mill Test Report, and, for EU shipments, CE marking and PED compliance. Third‑party inspection certificates (SGS, Bureau Veritas) are advisable for strategic nickel alloys.

What packaging and shipping formats are typical for these products?

Products are normally packed in wooden crates on pallets, suitable for 20‑ft or 40‑ft container loading. Common Incoterms used are FOB Shanghai or CIF destination port, with moisture‑resistant liners for corrosion‑sensitive alloys.

How can a buyer verify the material composition before placing an order?

Request the Mill Test Report that details chemical analysis per ASTM B466 or EN 10204 3.1, and compare the reported values against the UNS designation listed in the catalogue (e.g., 25 % Cr, 7 % Ni, 3 % Mo for S32750).
