316L stainless steel hexagonal pipe is a hollow hexagonal bar made from low-carbon austenitic stainless steel (316L). It offers excellent corrosion resistance (especially against chlorides and acids), high strength, and good machinability. It is widely used in chemical processing, marine environments, medical devices, and food processing industries.
Shape & Dimensions:
Hexagonal across flats (S): 6mm to 50mm
Wall thickness (T): 0.5mm to 5mm
Length: 1m to 6m (custom lengths available)
Surface Finish: Smooth inner/outer surfaces, polished or matte options.
International Standards:
ASTM A269/A312 (Seamless & Welded Tubes)
ASTM A554 (Stainless Steel Welded Mechanical Tubing)
EN 10296-2 (European Standard)
Chinese Standards:
GB/T 12770 (Welded Stainless Steel Pipes for Fluid Transport)
GB/T 14976 (Seamless Stainless Steel Pipes for Structural Use)
| Element | C≤ | Si≤ | Mn≤ | P≤ | S≤ | Cr | Ni | Mo | Fe |
|---|---|---|---|---|---|---|---|---|---|
| 316L | 0.03 | 0.75 | 2.00 | 0.045 | 0.03 | 16.0-18.0 | 10.0-14.0 | 2.0-3.0 | Balance |
Low Carbon (C≤0.03%) minimizes carbide precipitation and intergranular corrosion.
| Property | Tensile Strength (MPa) | Yield Strength (MPa) | Elongation (%) | Hardness (HB) |
|---|---|---|---|---|
| 316L | ≥485 | ≥170 | ≥40 | ≤217 |
Note: Cold working can enhance strength but may reduce ductility.
Material Preparation: 316L stainless steel billets are selected.
Forming:
Seamless Pipes: Hot extrusion or cold drawing.
Welded Pipes: Rolled into hexagonal shape and TIG welded.
Heat Treatment: Solution annealing (1050–1100°C) followed by rapid cooling to restore corrosion resistance.
Surface Treatment: Pickling, polishing, or passivation for improved finish.
Superior Corrosion Resistance: Resists pitting and crevice corrosion in harsh environments (e.g., seawater, acids).
High Strength-to-Weight Ratio: Suitable for structural applications.
Hygienic & Non-Toxic: Ideal for medical and food industries.
Aesthetic Appeal: Polished finish for architectural/decorative uses.
Standard: Plastic caps on ends, bundled with steel straps, wrapped in waterproof film.
Custom: Wooden crates for heavy-duty protection during transit.
Chemical Industry: Pipelines, heat exchangers, reactors.
Marine Engineering: Ship fittings, offshore platforms.
Medical Devices: Surgical instruments, implantable components.
Food Processing: Brewery tanks, conveyor systems.
Architecture: Handrails, decorative frameworks.
316L stainless steel hexagonal pipe combines durability, corrosion resistance, and versatility, making it a preferred choice for demanding industrial and commercial applications. Its compliance with international standards ensures reliability across global markets.
