Stainless Steel Tube: Seamless/Welded Corrosion-Resistant Tube for Industrial & Commercial Use

304 stainless steel 316L stainless steel Seamless Tube Welded Tube Corrosion Resistant

Stainless steel tube is a high-performance metal piping product crafted from corrosion-resistant stainless steel alloys (Cr ≥10.5%, combined with Ni, Mo, Ti, etc.). It complies with international standards (ASTM, JIS, GB, EN) and delivers exceptional rust resistance, durability, and formability.

Two Main Types:

  • Seamless Stainless Steel Tube: Manufactured via hot extrusion or cold drawing, offering superior structural integrity and high pressure resistance.
  • Welded Stainless Steel Tube: Formed by welding stainless steel strips (ERW/TIG), cost-effective and suitable for general industrial use.

❓ Frequently Asked Questions
Q: What's the difference between 304 and 316L stainless steel tubes?
A: 316L contains molybdenum (Mo) for better resistance to saltwater, acids, and pitting corrosion; 304 is more economical for general use such as water pipelines and architecture.
Q: Seamless vs. welded stainless steel tube - Which is better?
A: Seamless tubes offer higher pressure resistance and precision for critical applications, while welded tubes are lower cost and available in larger outer diameter options for general use.
Q: Are stainless steel tubes magnetic?
A: Austenitic grades like 304 and 316L are typically non-magnetic. Ferritic (430) or Duplex (2205) grades are slightly magnetic, which does not impact their performance.
Q: Can I use stainless steel tubes for drinking water?
A: Yes, 304 and 316L tubes comply with FDA/NSF standards. they are non-toxic and corrosion-resistant, making them safe for drinking water systems.
Q: Do you offer custom sizes and finishes?
A: Absolutely. We provide customization for outer diameter (6mm-1200mm), wall thickness (0.3mm-20mm), length, and various finishes like 2B, BA, or electrolytic polish.
Q: What standards do your tubes comply with?
A: Our products are 100% compliant with international standards including ASTM A213, A312, JIS G3459, and GB/T 14976, ensuring global reliability.
