About Kcm Special Steel Co., Ltd. - Stainless Steel Pipes & Pipe Fittings Supplier in China

Based in China, Kcm Special Steel Co., Ltd. currently lists eight distinct stainless steel pipe and fitting products in its catalogue. The portfolio includes seamless pipes, duplex and super‑duplex pipes, thick‑wall pipe and tube, standard pipe fittings, and nickel‑based alloy (Incoloy 825 and 800H) pipe and fittings. Each item is classified under HS code 7304.11, 7306.40, 7307.23 or 7307.29, covering the primary tariff headings for stainless steel tubes, pipes and fittings. The material specifications reference grades such as 304/304L, 316/316L, 321, 347, duplex 2205, super duplex S32750/S32760, and nickel alloys Incoloy 825 and 800H.

The catalogue groups the products into three top categories: Stainless Steel Pipes & Pipe Fittings, Flanges, and Stainless Steel Tubes, reflecting the typical segmentation of the stainless steel pipe market. The listed products address applications ranging from petrochemical and oil‑gas transport to food processing and architectural uses, where corrosion resistance and high temperature performance are required. The HS code families (7304, 7306, 7307) indicate that the goods are treated as finished pipe and fitting articles for customs purposes. Buyers can therefore expect the items to be shipped in standard 20‑ft or 40‑ft containers, often bundled on wooden pallets.

Product Range and Specialties of Kcm Special Steel Co., Ltd.

The catalogue offers seamless pipes in grades 304, 304L, 316, 316L, 321, 347 and duplex 2205 (UNS S32205), as well as super‑duplex pipe (UNS S32750/S32760) and thick‑wall pipe & tube covering a broad selection of stainless steel grades (201, 202, 301, 304, 304L, 310S, 316, 316L, 317L, 321, 347, Duplex). In the pipe‑fitting segment, standard stainless steel fittings are supplied in 304, 304L, 316, 316L, 321, 347 and duplex S31803/S32750, while nickel‑alloy fittings are available in Incoloy 825 and Incoloy 800H. Industry standards such as ASTM A312 (seamless and welded pipe), ASTM A269 (seamless tube) and EN 10210 (hot‑finished tubes) typically govern dimensions from DN 15 mm up to DN 2000 mm and wall thicknesses up to 200 mm, with pressure ratings from PN 10 to PN 640.

Typical grades for stainless steel pipe include austenitic 304/304L and 316/316L for general corrosion resistance, duplex 2205 for higher strength and chloride resistance, and super‑duplex S32750/S32760 for maximum corrosion and pitting resistance in aggressive media. Nickel alloys such as Incoloy 825 (high‑temperature oxidation resistance) and Incoloy 800H (creep resistance) are specified to ASTM B444 and ASTM B564 standards. Buyers often request surface finishes of 2B, 4B or polished, and may specify end‑connections (butt‑welded, threaded, or flanged) according to project requirements.

Trade and Export Information - Kcm Special Steel Co., Ltd.

China is one of the world’s largest exporters of stainless steel pipe, tube and fittings, with major destination regions including Southeast Asia, the Middle East, Europe and North America. The products fall under HS chapter 73, where tariff treatment differs by sub‑heading: 7304 covers seamless pipe and tube, 7306 covers thick‑wall pipe and tube, and 7307 covers fittings. Importers commonly require ISO 9001 quality‑management certification, EN 10204 3.1 mill test reports, and where applicable CE marking for EU markets. Typical logistics involve FOB Shanghai or Ningbo, with loads consolidated in 20‑ft or 40‑ft containers, pallets secured with steel straps, and protective wrapping for corrosion control during transit.

Sourcing from Kcm Special Steel Co., Ltd. - Buyer Guidance

When sourcing from this supplier, request a mill test report (MTR) that details chemical composition, tensile strength, elongation and impact values in accordance with the relevant ASTM or EN standard. Verify that the material grade matches the project specification (e.g., ASTM A312 316L or UNS S32205 for duplex) and confirm dimensions, wall thickness, pressure rating and surface finish before finalising the order. It is advisable to ask for a certificate of origin, ISO 9001 certificate and any third‑party inspection reports, as these documents are standard for stainless steel pipe imports from China.

What stainless steel grades are offered in the seamless pipe line?

The seamless pipe line includes grades 304, 304L, 316, 316L, 321, 347 and duplex grade 2205 (UNS S32205). These correspond to the austenitic and duplex families commonly used in corrosive environments.

Which HS codes apply to the listed pipe and fitting products?

Products are classified under HS 7304.11 for seamless pipe, tube and duplex pipe, HS 7306.40 for thick‑wall pipe and tube, HS 7307.23 for standard stainless steel fittings and Incoloy 825 fittings, and HS 7307.29 for Incoloy 800H fittings.

Does Kcm Special Steel hold any certifications for its stainless steel products?

No specific certifications are listed in the supplied data. Buyers should request the supplier’s ISO 9001 quality‑management certificate, mill test reports and EN 10204 3.1 inspection certificates before purchase.

What typical standards govern the dimensions and pressure ratings of the stainless steel pipes?

International standards such as ASTM A312 (seamless and welded pipe), ASTM A269 (seamless tube) and EN 10210 (hot‑finished steel tubes) define nominal diameters from 15 mm to 2000 mm, wall thicknesses up to 200 mm, and pressure ratings from PN 10 to PN 640.

How are the products usually packaged for overseas shipment?

Pipes and tubes are generally coiled or bundled, secured with steel straps and placed on wooden pallets. Fittings are packed in double‑wall cartons. Full loads are loaded into 20‑ft or 40‑ft containers, often under FOB Shanghai or Ningbo terms.

What documentation is typically required for customs clearance of HS 7304‑7307 items from China?

Importers normally need a commercial invoice, packing list, bill of lading, certificate of origin and a mill test report confirming material grade, chemical composition and mechanical properties. Additional certificates such as ISO 9001 or CE marking may be requested by the destination country.

What are common lead times and minimum order quantities for these stainless steel products?

Lead times generally range from 30 to 60 days after order confirmation, depending on product size and grade. Minimum order quantities are often expressed as 1 metric ton per grade or a batch of 10 pieces for fittings, but exact figures should be verified with the supplier.
