321 Stainless Steel C Channels

321 Stainless Steel C Channels are premium structural components manufactured from electric-furnace processed austenitic stainless steel. These channels feature a distinctive C-shaped cross-section and contain 18% chromium, 8% nickel, and a significant titanium addition. The titanium forms stable carbides, preventing chromium carbide precipitation and ensuring superior corrosion resistance, especially in temperatures ranging from 800°F to 1600°F.

Superior Properties and Applications of 321 Stainless Steel Channels

These Stainless Steel C Channels excel in welded applications and elevated temperature operations where re-annealing isn't practical. Their unique composition makes them ideal for:

• Aircraft and missile industries
• Marine engineering
• Construction projects
• Manufacturing equipment
• Structural support systems

Corrosion Resistance

321 Stainless Steel C Channels demonstrate exceptional resistance to intergranular corrosion and superior weld area protection. While they exhibit slightly lower atmospheric corrosion resistance compared to Types 302 or 304 in the annealed condition, their overall performance in demanding environments remains outstanding.

These channels are manufactured through hot rolling or cold bending processes and can be produced with various surface finishes including polished, brushed, or mill finish, depending on specific application requirements and aesthetic needs.

All our 321 Stainless Steel Channels are certified by SGS, ISO, and comply with ROHS standards, ensuring consistent quality and reliability for your structural applications.
