Stainless Steel 316L Coiled Tubing – Technical Specifications
SS TP316L coiled tubes – Chemical Composition
SS 316L is a low-carbon austenitic stainless steel, ideal for coiled tubes used in chemical, marine, and industrial environments. The combination of Cr, Ni, and Mo ensures excellent corrosion resistance, especially against chlorides and acids.
| Element | Composition (%) | Notes |
|---|---|---|
| Carbon (C) | 0.03 max | Low carbon reduces carbide precipitation and improves corrosion resistance. |
| Chromium (Cr) | 16.0 – 18.0 | Provides corrosion and oxidation resistance. |
| Nickel (Ni) | 10.0 – 14.0 | Enhances ductility, toughness, and general corrosion resistance. |
| Molybdenum (Mo) | 2.0 – 3.0 | Improves resistance to pitting and crevice corrosion in chloride environments. |
| Manganese (Mn) | 2.0 max | Acts as a deoxidizer and improves hardness slightly. |
| Silicon (Si) | 1.0 max | Adds oxidation resistance. |
| Phosphorus (P) | 0.045 max | Kept low to prevent brittleness. |
| Sulfur (S) | 0.03 max | Low sulfur reduces susceptibility to cracking and improves weldability. |
| Iron (Fe) | Balance | Base metal providing structural integrity. |
