ASTM A268 /ASME SA268 TP410 tubes are known for their excellent corrosion resistance， particularly in mildly corrosive environments. They offer good strength， hardness， and wear resistance， making them suitable for high-temperature applications. TP410 tubes are commonly used in heat exchangers， boilers， condensers， and other industrial applications where resistance to corrosion， high temperatures， and mechanical stresses is required.
| ASTM A268 /ASME SA268 TP410 tubes are primarily composed of the following elements: |
| 1. Chromium (Cr): 11.5% to 13.5% |
| 2. Carbon (C): Maximum 0.15% |
| 3. Nickel (Ni): Maximum 0.75% |
| 4. Manganese (Mn): Maximum 1.0% |
| 5. Silicon (Si): Maximum 1.0% |
| 6. Phosphorus (P): Maximum 0.04% |
| 7. Sulfur (S): Maximum 0.03% |
| ASTM A268 /ASME SA268 TP410 tubes Mechanical Properties: |
| The mechanical properties of SA-268 TP410 tubes are typically as follows: |
| – Tensile Strength: 485 MPa (70，300 psi) minimum |
| – Yield Strength: 275 MPa (40，000 psi) minimum |
| – Elongation: 20% minimum |
| – Hardness: Rockwell B hardness of 95 maximum |
