Hemaokang Steel (Shandong) Co., Ltd. is a professional manufacturer and exporter of stainless steel products, committed to delivering high-quality ASTM A269 304 Stainless Steel Welded Tubes with 2B Mill Finish. Our tubes are precision-engineered with wall thicknesses ranging from 0.5mm to 2mm and outer diameters from 10mm to 200mm, meeting the rigorous demands of various industrial applications. Backed by our ISO9001-certified management system and extensive export experience (annual export value US$50-100 million), we ensure consistent quality, reliable supply, and competitive pricing for global buyers.

Product Overview
This ASTM A269 304 stainless steel welded tube combines excellent corrosion resistance, good weldability, and a smooth 2B mill finish surface. It is widely used in industries such as chemical processing, oil & gas, food & beverage, pharmaceutical, and construction. The tube is manufactured from high-quality 304 stainless steel coils, welded using advanced TIG technology, and then annealed and pickled to achieve the 2B finish. The dimensional accuracy and consistent wall thickness make it ideal for bending, flaring, and other forming operations.

Key Features & Benefits

Superior Corrosion Resistance: 304 stainless steel offers excellent resistance to oxidation, acids, and chlorides, ensuring long service life in harsh environments.
Precise Dimensions: Outer diameter tolerance: ±0.1mm (for OD ≤ 50mm), ±0.15mm (for OD > 50mm); wall thickness tolerance: ±0.05mm. This ensures easy installation and compatibility with standard fittings.
Smooth 2B Surface Finish: The 2B mill finish provides a uniform, matte appearance that is easy to clean and maintain, suitable for sanitary or aesthetic applications.
Excellent Weldability: The welded seam is fully annealed and has a smooth transition, minimizing risk of cracking or leakage under pressure.
Customizable Length: Standard lengths are 3m, 4m, or 6m, but we can cut to your exact specifications (minimum 0.5m) upon request.
Wide Application Range: Suitable for heat exchangers, condensers, evaporators, food processing equipment, pharmaceutical piping, and general structural applications.

Frequently Asked Questions (FAQ)

Q: What is the minimum order quantity (MOQ) for this product?
A: Our MOQ is typically 500 kg per size, but we can accommodate smaller trial orders for new customers. Please contact our sales team.
Q: Can I get a sample before placing a bulk order?
A: Yes, we offer free samples (freight collect) for evaluation. Sample tubes are available in standard sizes upon request.
Q: Do you provide full traceability and mill test certificates?
A: Absolutely. Every shipment can be accompanied by a mill test certificate (MTC) as per EN 10204 3.1, and our ISO9001 system ensures traceability.
Q: What is the typical lead time?
A: For standard sizes (OD ≤ 100mm), lead time is 15-20 working days. For larger diameters or custom lengths, it may be 20-25 working days.
Q: Is the 2B finish suitable for food contact applications?
A: Yes, the 2B mill finish is smooth and non-porous, meeting sanitary requirements for food and beverage processing. However, for highly abrasive environments, a 4 finish may be recommended.
Q: Can you supply tubes with a polished (mirror) finish instead of 2B?
A: Yes, we offer additional surface finishes such as 4 (brushed) or 8K (mirror) upon request, subject to MOQ and pricing.
Q: Do you export to my country? What are the shipping terms?
A: We export to all major markets worldwide. Common shipping terms are FOB, CIF, or CFR. We can arrange door-to-door logistics for small orders.
Q: How do you ensure the quality of the welded seam?
A: Each tube undergoes non-destructive testing (NDT) such as eddy current or hydrostatic test, as per ASTM A269 requirements. We also perform visual inspection and dimensional checks.
