321 Stainless Steel C Channels: Technical Specifications and Applications 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: Structural integrity at high temperatures. Marine engineering: Excellent corrosion resistance in marine environments. Construction projects: Reliable performance in demanding conditions. Manufacturing equipment: Durability in heavy-duty machinery. Structural support systems: Versatile use across various industries. Technical Specifications Standards: GB, AISI, ASTM, DIN, EN, JIS, SUS Grade Designations: AISI: 321 UNS: S32100 EN/DIN: 1.4541 (X6CrNiTi18-10) JIS: SUS 321 Dimensional Range Thickness (mm) Width (mm) Length (mm) Surface Finish Options 1.5 - 25 37 - 88 1000 - 12000 Black, galvanized, coated, painted, or customized Polished, brushed, mill finish 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.
