316L Stainless Steel Hexagonal Pipe – Technical Overview

1. Introduction of 316L Hexagonal Stainless Steel Pipe

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.

2. Specifications of 316L Hexagonal Stainless Steel Pipe

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.

3. Standards Compliance of 316L Hexagonal Stainless Steel Pipe

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)

4. Chemical Composition (%) of 316L Hexagonal Stainless Steel Pipe

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.

5. Mechanical Properties of 316L Hexagonal Stainless Steel Pipe

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.

6. Manufacturing Process of 316L Hexagonal Stainless Steel Pipe

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.

7. Key Features of 316L Hexagonal Stainless Steel Pipe

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.

8. Packaging of 316L Hexagonal Stainless Steel Pipe

Standard: Plastic caps on ends, bundled with steel straps, wrapped in waterproof film.
Custom: Wooden crates for heavy-duty protection during transit.

9. Applications of 316L Hexagonal Stainless Steel Pipe

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.

Summary

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.
