| High Light | Marine Stainless Steel Square Tube ，316L Stainless Steel Square Tube | ||
316 stainless steel square tube is a hollow structural section with four equal sides. Grade 316 contains molybdenum, which provides superior corrosion resistance against chlorides, salt water, and harsh chemicals.
Our 316 square tubes are ideal for marine, coastal, and chemical processing applications where standard 304 stainless steel may not perform adequately. Both welded and seamless options are available.
| Parameter | Details |
|---|---|
| Standard | ASTM A554, A312, A269, EN 10296, JIS G3446, GB/T 12770 |
| Grade | 316, 316L |
| Size (Width x Width) | 10 mm x 10 mm – 200 mm x 200 mm |
| Wall Thickness | 0.8 mm – 6.0 mm |
| Length | 3000 mm, 4000 mm, 6000 mm (custom cut available) |
| Process | Welded (ERW) or Seamless (Cold Drawn) |
| Surface Finish | Mill finish, Pickled, Polished (No.4, BA, Mirror), Brushed |
| Element | Grade 316 | Grade 316L |
|---|---|---|
| Carbon (C) | ≤ 0.08 | ≤ 0.03 |
| Silicon (Si) | ≤ 1.00 | ≤ 1.00 |
| Manganese (Mn) | ≤ 2.00 | ≤ 2.00 |
| Phosphorus (P) | ≤ 0.045 | ≤ 0.045 |
