304 Stainless Steel Pipe is a widely used austenitic stainless steel pipe known for its excellent corrosion resistance, good strength, and superior formability. It offers a smooth surface, good weldability, and reliable performance in various industrial environments. 304 stainless steel pipe is available in seamless and welded forms and is widely used for fluid transportation, structural applications, food processing, chemical equipment, and general industrial piping.
Chemical Composition
| Element | Composition (%) |
| Carbon (C) | ≤ 0.08 |
| Silicon (Si) | ≤ 1.00 |
| Manganese (Mn) | ≤ 2.00 |
| Phosphorus (P) | ≤ 0.045 |
| Sulfur (S) | ≤ 0.030 |
| Chromium (Cr) | 18.0–20.0 |
| Nickel (Ni) | 8.0–11.0 |
