316/316L Stainless Steel Channels

Corrosion Resistance: Excellent resistance to pitting and crevice corrosion in chloride-containing environments, seawater, and aggressive chemical media, thanks to 2–3% molybdenum content. The low carbon 316L version provides enhanced resistance to intergranular corrosion after welding.

High Strength-to-Weight Ratio: Excellent load-bearing capacity with good ductility for structural applications, allowing for lighter frameworks without compromising strength.

Superior Weldability: 316L grade ensures low carbon content for superior weld performance, with reduced risk of intergranular corrosion in welded fabrications. Suitable for TIG, MIG, and arc welding.

Excellent Formability: Can be bent, cut, drilled, and fabricated to meet specific project requirements.

Precision Dimensional Tolerances: Tight tolerances on web height, flange width, thickness, and straightness ensure consistent quality for structural assemblies.

Smooth Surface Quality: Available in annealed and pickled finish (standard), polished, or brushed finishes for architectural and exposed applications.

Multiple Channel Types: U channels (standard channels), C channels, parallel flange channels, and tapered flange channels available.

Aesthetic Appearance: Bright silver finish provides excellent visual appeal for exposed structural elements in architectural applications.

International Certifications: Channels can be certified by ABS, BV, DNV, LR, GL, RINA, CCS, KR, and NK, and comply with NORSOK standards for offshore projects.

Both 316 and 316L stainless steel channels exhibit excellent corrosion resistance and mechanical properties. The lower carbon content in 316L minimizes carbide precipitation during welding, providing enhanced resistance to intergranular corrosion compared to standard 316, especially in welded structural applications.

Heat Treatment Condition:
Both 316 and 316L stainless steel channels are normally supplied in the annealed and pickled condition. Solution annealing at 1040–1080°C followed by rapid cooling restores full corrosion resistance, relieves internal stresses from rolling, and ensures optimal ductility for fabrication.

Delivery Condition:
Channels are normally supplied in annealed and pickled condition, providing a clean, smooth surface and excellent corrosion resistance. Upon request, polished or brushed finishes can be provided for architectural applications.

Note: Custom sizes, unequal channels, and longer lengths available upon request. Section modulus values are approximate and vary by manufacturing method.

Raw Material Selection: High-quality 316/316L stainless steel billets or slabs from certified mills with certified chemical composition.

Heating: Billets heated to 1150–1250°C for hot rolling.

Hot Rolling: Heated billets passed through roughing and finishing stands (continuous rolling mill) to form channel shape.

Cooling: Controlled cooling to prevent distortion and maintain dimensional accuracy.

Straightening: Roller straightening to ensure straightness tolerance within 2 mm per meter.

Solution Annealing: Heat treatment at 1040–1080°C for optimal corrosion resistance.

Pickling & Passivation: Removal of oxides and creation of passive film for enhanced corrosion protection.

Cutting: Cut to standard 6-meter lengths (or custom lengths per order).

Inspection & Marking: Each bundle inspected, marked with grade, heat number, dimensions, and standard.

Chemical Analysis: Spectrometer or PMI verification of alloy elements (Cr, Ni, Mo).

Mechanical Testing: Tensile strength, yield strength, elongation, hardness per ASTM A370.

Dimensional Inspection: Web height, flange width, thickness, squareness, straightness, length.

Surface Inspection: Visual check for surface defects, cracks, and consistency.

Intergranular Corrosion Test: ASTM A262 Practice E for 316L (upon request).

Positive Material Identification (PMI): Upon customer request.

Ultrasonic Testing (UT): For internal flaw detection (upon request).

Third-Party Inspection: SGS, BV, DNV, TUV, LR, ABS available upon customer request.

1. What is the difference between U channel and C channel?
U channel has tapered flanges (wider at the tip) typical of hot-rolled sections. C channel has parallel flanges (equal thickness throughout), often from cold-forming or precision hot-rolling. Both are available in 316/316L stainless steel.

2. Can 316L stainless steel channels be welded?
Yes, 316L has excellent weldability with low carbon content to prevent intergranular corrosion. Standard welding procedures (TIG, MIG, arc) are suitable.

3. What is the standard length for stainless steel channels?
Standard length is 6 meters (20 feet). Custom lengths from 1m to 12m available upon request.

4. Are 316L channels suitable for marine environments?
Yes, 316L offers excellent resistance to seawater corrosion and is widely used in marine and offshore applications. ABS/DNV/LR certifications available.

5. Can you supply channels with custom hole drilling?
Yes. We offer custom fabrication including hole drilling, notching, cutting, and welding per your specifications.
