Key Performance & Technical Details
Tensile & Bend Strength
Our stainless steel c channel grades, including AISI 316L and 310S, deliver tensile strengths up to 860 MPa (web1), ideal for structural frameworks requiring resistance to deformation. For example, AISI 316L’s molybdenum content enhances stress corrosion cracking resistance, making it suitable for stainless steel unistrut channel systems in marine environments. The bend strength of AISI 430 (450 MPa yield) ensures durability in load-bearing applications like industrial shelving.
Weight Calculation
Calculate the weight of a stainless steel c channel using:
Weight (kg) = [(Height × Width × Thickness) – (Web Thickness²)] × Length × Density (7.93 g/cm³)
For a 50mm × 30mm × 3mm channel (6m length), weight ≈ 8.2 kg. Custom calculators are available for complex profiles (web4).
Why Stainless Steel Rusts
Despite inherent corrosion resistance, factors like:
- Chloride Exposure: Coastal or chemical environments degrade chromium oxide layers (web1).
- Galvanic Corrosion: Contact with dissimilar metals (e.g., carbon steel) accelerates oxidation.
- Poor Surface Finish: Rough surfaces trap moisture and contaminants (web5).
Our channels undergo electrolytic passivation (web4) to restore protective chromium layers, validated by salt spray tests exceeding 1,000 hours.
Identification & Marking
Each stainless steel c channel is laser-etched with:
- Grade (e.g., AISI 316L)
- Batch ID (for ISO 9001 traceability)
- Certification Marks (ASTM A554, JIS G4303)
QR codes link to mill test reports (web4), ensuring compliance with global export standards.
