Material Grade SS410 stainless steels is general-purpose martensitic stainless steel containing 11.5% chromium， which provide good corrosion resistance properties. However， the corrosion resistance of grade 410 steels can be further enhanced by a series of processes such as hardening， tempering and polishing. Quenching and tempering can harden grade 410 steels. They are generally used for applications involving mild corrosion， heat resistance and high strength.
The tubes shall have a hardness number that will not exceed the prescribed Brinell and Rockwell hardness values， TP410， TP430 and TP439 max Rockwell hardness 90HRB， Test report required certification conform to Specification A1016/A1016M.
ASTM A268 TP410 (1.4006， UNS S41000， X12Cr13) Martensitic Steel Seamless Tube Test Scope:
| Tension test; |
| Flaring test (for seamless tubes); |
| Flange test (for welded tubes); |
| Hardness test; |
| Reverse flattening test; |
| Intergranular corrosion test; and |
| Hydrostatic or nondestructive electric test. |
| ASTM A268 /ASME SA268 TP410 Composition: |
| 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 |
ASTM A268 /ASME SA268 TP410 exhibits good corrosion resistance in mildly corrosive environments， including atmospheric conditions and many organic and inorganic chemicals. However， it may not be suitable for highly corrosive environments containing strong acids or chlorides. In such cases， a more corrosion-resistant stainless steel grade， such as TP316 or TP304， may be preferred.
| ASTM A268 /ASME SA268 TP410 tubes are commonly used in various heat exchanger applications， such as: |
| – Shell and tube heat exchangers |
| – Condensers |
| – Boilers |
| – Process heaters |
| – Refinery equipment |
| – Petrochemical plants |
| – Power generation facilities |
| These tubes are suitable for applications where resistance to corrosion， high temperatures， and mechanical stresses is required. TP410 offers good strength， hardness， and wear resistance， making it suitable for demanding environments. |
