| Element | ASTM A213 TP316L Requirements | Typical Values |
|---|---|---|
| Carbon (C) | ≤ 0.03% | 0.02% |
| Manganese (Mn) | ≤ 2.00% | 1.50% |
| Phosphorus (P) | ≤ 0.045% | 0.030% |
| Sulfur (S) | ≤ 0.030% | 0.020% |
| Silicon (Si) | ≤ 1.00% | 0.75% |
| Chromium (Cr) | 16.0-18.0% | 17.2% |
| Nickel (Ni) | 10.0-14.0% | 12.5% |
| Molybdenum (Mo) | 2.0-3.0% | 2.5% |
| Nitrogen (N) | ≤ 0.10% | 0.05% |
| Iron (Fe) | Balance | Balance |
Notes: Low carbon (0.03% max) prevents carbide precipitation during welding. Molybdenum (2-3%) enhances corrosion resistance, especially against chlorides.
| Property | ASTM A213 TP316L Requirements | Typical Values |
|---|---|---|
| Tensile Strength (MPa) | ≥ 485 | 515-620 |
| Yield Strength (0.2% Offset, MPa) | ≥ 170 | 205-310 |
| Elongation (% in 50mm) | ≥ 35 | 40-50 |
| Hardness (Rockwell B) | ≤ 95 HRB | 80-90 HRB |
| Hydrostatic Test Pressure | As per ASTM A213 (varies by size) | -- |
Notes: High elongation (≥35%) ensures ductility for forming/welding. Low hardness improves machinability and reduces cracking risk.
| Property | TP316L (A213) | TP316 (A213) | TP304L (A213) |
|---|---|---|---|
| Carbon (Max) | 0.03% | 0.08% | 0.03% |
| Mo Content | 2-3% | 2-3% | None |
| Tensile Strength (MPa) | ≥485 | ≥515 | ≥485 |
| Corrosion Resistance | Excellent (acid/chloride) | Good | Moderate |
ASTM A213 TP316L tubes are ideal for corrosive, high-temperature, or high-purity applications where welding or chloride exposure is a concern. Common alternatives like 304L lack molybdenum, making TP316L the go-to for aggressive media (e.g., seawater, acids).
