Product Overview
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.). Available in seamless (hot-extruded/seamless drawn) and welded (ERW/TIG) configurations, it complies with international standards (ASTM, JIS, GB, EN) and delivers exceptional rust resistance, durability, and formability. From food processing pipelines to chemical plant systems, architectural handrails to automotive exhausts, stainless steel tube is the go-to choice for industries demanding long-term reliability in harsh or precision-required environments.
Core Types & Key Advantages
Material Foundation: The chromium content forms a dense, self-healing oxide film on the surface, blocking corrosion from moisture, chemicals, and high temperatures.
Two Main Types:
  • Seamless Stainless Steel Tube: Manufactured via hot extrusion or cold drawing (no weld seams), offering superior structural integrity, high pressure resistance, and tight dimensional tolerance. Ideal for high-pressure, high-temperature, or critical precision applications (thickness: 0.5mm-20mm).
  • Welded Stainless Steel Tube: Formed by welding stainless steel strips (ERW/TIG welding), cost-effective, high production efficiency, suitable for general industrial and commercial use (thickness: 0.3mm-12mm).
Unmatched Advantages:
  • Extreme corrosion resistance (adapts to fresh water, saltwater, acids, alkalis, and harsh industrial media).
  • High tensile strength & ductility (easy to cut, bend, weld, and fabricate into complex shapes).
  • Hygienic & easy to clean (meets FDA/3A standards for food/medical use, no toxic leaching).
  • Long service life (low maintenance, no need for anti-corrosion coating).
  • Aesthetic versatility (matte, mirror, brushed surfaces for decorative or functional use).
Common Surface Finishes: 2B (matte, industrial standard), BA (mirror polish), No.4 (brushed), electrolytic polish, pickling passivation-customized for your use case.
Hot-Selling Stainless Steel Grades
Grade Alloy Key Features Max Service Temp Core Advantages Typical Applications
304/304L Cr18-Ni8, low carbon (304L) ≤870ºC Cost-effective, general corrosion resistance, food-safe Food processing pipelines, architectural handrails, water treatment systems, kitchen equipment
316/316L Cr18-Ni12-Mo2, low carbon (316L) ≤870ºC Superior corrosion resistance (saltwater/chemicals), anti-pitting Marine pipelines, chemical tanks, medical devices, offshore platforms, pharmaceutical equipment
321 Cr18-Ni9-Ti ≤900ºC Heat-resistant, avoids intergranular corrosion High-temperature pipelines, furnace tubes, aerospace components, boiler systems
310S Cr25-Ni20 ≤1150ºC Ultra-high temperature resistance, oxidation-resistant Industrial furnaces, heat exchangers, high-temperature exhaust systems
2205 (Duplex) Cr22-Ni5-Mo3 ≤315ºC High strength + corrosion resistance (2x stronger than 304/316L) Oil & gas pipelines, chemical reactors, seawater desalination plants
430 Cr17 (ferritic) ≤815ºC Economical, good formability, magnetic Appliance tubes, decorative structures, non-critical industrial pipelines

  • Architecture & Construction: Handrails, balustrades, curtain wall supports, decorative tubes, and HVAC systems (304/430, 2B/BA/Brushed finishes).
  • Marine & Offshore: Ship hull piping, offshore platform pipelines, seawater cooling systems, and coastal structures (316L/2205).
  • Medical & Pharmaceutical: Surgical instrument components, cleanroom pipelines, and drug processing equipment (316L, electrolytic polish).
  • Automotive & Aerospace: Exhaust systems, fuel lines, and aerospace hydraulic tubes (304/321/310S).
  • Water Treatment: Drinking water pipelines, wastewater treatment systems, and desalination plants (304/316L).
Procurement Guide
Select the Grade:
  • General use + food/Drinking water: 304/304L (cost-effective, corrosion-resistant).
  • Saltwater/chemicals/harsh environments: 316/316L (Mo-enhanced protection).
  • High temperature (≥900ºC): 321/310S (heat-stable alloys).
  • High strength + corrosion resistance: 2205 duplex (heavy-duty industrial use).
  • Budget-friendly non-critical use: 430 (ferritic stainless steel).
Choose Seamless vs. Welded:
  • High pressure/high temperature/critical applications: Seamless (no weld weak points).
  • General industrial/commercial use: Welded (cost-effective, large OD available).
Confirm Dimensions: Specify OD, WT, length (fixed 6m/12m or custom cut-to-length), and schedule (e.g., Schedule 40 for standard pressure).
Surface Finish: 2B (default for industrial pipelines), BA (mirror for decoration), electrolytic polish (medical/food), pickling passivation (corrosion protection).
Quality Requirements: Request mill test report (MTR) for chemical composition/mechanical properties; non-destructive testing (NDT: ultrasonic, eddy current) for high-pressure projects.
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 (e.g., water pipelines, architecture).
Q: Seamless vs. welded stainless steel tube-Which is better?
A: Seamless = higher pressure resistance + precision (critical applications); welded = lower cost + larger OD options (general use).
Q: Are stainless steel tubes magnetic?
A: 304/316L (austenitic) = non-magnetic; 430 (ferritic)/2205 (duplex) = slightly magnetic (no impact on performance).
Q: Can I use stainless steel tubes for drinking water?
A: Yes-304/316L tubes comply with FDA/NSF standards, non-toxic and corrosion-resistant, safe for drinking water.
Q: Do you offer custom sizes and finishes?
A: Absolutely-we customize OD (6mm-1200mm), WT (0.3mm-20mm), length, and finishes (2B/BA/electrolytic polish) to your project needs.
