| High Light | ASTM A213 TP321 seamless tube ，S32100 corrosion resistant tube ，high-temperature stainless steel tube | ||
ASTM A213 TP321 is a seamless austenitic stainless steel tube specifically engineered for high-temperature and corrosive service environments. The grade is stabilized with titanium, which provides exceptional resistance to intergranular corrosion and makes it suitable for a wide range of demanding industrial applications, from boilers to chemical processing equipment.
This product is manufactured in strict compliance with the latest international standards:
TP321 is a titanium-stabilized derivative of the classic 18-8 (Cr-Ni) stainless steel. The addition of titanium (at least 5 times the carbon content) prevents chromium carbide precipitation at grain boundaries during high-temperature exposure, thereby maintaining its corrosion resistance.
A typical chemical composition is shown in the table below:
| Carbon (C) | Manganese (Mn) | Phosphorus (P) | Sulfur (S) | Silicon (Si) | Chromium (Cr) | Nickel (Ni) | Titanium (Ti) |
|---|---|---|---|---|---|---|---|
| 0.08% | 2.00% | 0.045% | 0.030% | 1.00% | 17.0 - 19.0% | 9.0 - 12.0% | 5C - 0.70% |
ASTM A213 TP321 tubes are required to undergo mechanical testing, including tension and flattening tests, and are supplied in a heat-treated condition. The following table outlines its key mechanical properties at room temperature.
| Property | Typical Value | Standard / Condition |
|---|---|---|
| Tensile Strength | ≥ 515 MPa (75 ksi) | ASTM A213 |
| Yield Strength (0.2% Offset) | ≥ 205 MPa (30 ksi) | ASTM A213 |
| Elongation | ≥ 35% | In 2 inches or 50 mm |
| Hardness | ≤ 192 HB / 90 HRB | Brinell or Rockwell B |
| Primary Advantage | Excellent high-temperature strength & intergranular corrosion resistance | Stabilized with Titanium |
Due to its stability and strength under heat, TP321 seamless tubes are critical components in several heavy industries:
