Same as 304 hex tubes,there are also 3 types of hex tubes

1.Outside shape hex,inside hole round shapes

2.Outside shape hex,inside hex shapes

3.Outside round like round pipes or round bars shape,inside hexagonal shapes

316 hex tube Surface:acid washing like NO.1,polished or brushed or sandblasting

Length:usually per length 4meter up to 5 meters,fixed length also could accept but with higher cost

Cutting to length service supplied follow your request.

Applications of 316 Stainless Steel Hex Tubes as below:

1. Marine & Coastal Environments

· Handrails, ladders, and guardrails on ships, docks, and offshore platforms.

· Coastal architecture (e.g., beachfront railings, lamp posts, building facades) where saltwater exposure is common.

2. Industrial & Chemical Processing

· Fluid and gas transfer lines in chemical, petrochemical, and pharmaceutical plants.

· Heat exchanger components and pressure vessel fittings.

· Food processing equipment (dairy, brewing, etc.) requiring sanitary conditions and corrosion resistance.

3. Architectural & Structural

· Decorative structural elements – modern staircases, curtain walls, balustrades, and furniture frames.

· The hex shape provides a flat surface for easy bolting, clamping, or welding, and offers an aesthetic geometric look.

4. Mechanical & Precision Parts

· Wrenches, tool handles, and machine shafts – the hexagonal profile improves torque transfer and grip.

· Hydraulic and pneumatic system components (fittings, connectors) where a leak-tight, corrosion-resistant tube is needed.

· Aerospace instrumentation lines – due to uniform stress distribution and high reliability.

5. Instrumentation & Pressure Gauges

· Used in gauge lines, impulse lines, and control panels where precise fit and resistance to aggressive media are required.

Important Notes· 316 Hex tube vs. 316 hex bar

316 hex Tube =316 hollow (for fluid/gas flow, lighter weight)

316 Bar =316 hex solid (for high-strength fasteners, axles, etc.)

316 vs. 316L

316L has lower carbon content → better weldability and resistance to intergranular corrosion after welding. Preferred for welded applications.

While 316 is often called "marine grade", it is not recommended for long-term full immersion in seawater (e.g., underwater hull parts). For such conditions, duplex stainless steel (e.g., 2205) or super austenitic grades (e.g., 254 SMO) are better.If you like details on standard sizes,wall thicknesses,or typical suppliers?please contact us.
