Heat Exchanger Tube ASTM A269 TP321 SMLS Tube
ASTM A269 TP321 seamless tubes are high-quality stainless steel tubes made from grade 321, a titanium-stabilized austenitic stainless steel. These tubes are designed for use in high-temperature and highly corrosive environments, especially in industries requiring excellent resistance to intergranular corrosion and oxidation.
Key Features of ASTM A269 TP321 Seamless Tubes:
1. High-Temperature Resistance:
TP321 is specifically formulated to resist scaling and maintain mechanical properties at elevated temperatures, making it ideal for applications involving heat.
2. Corrosion Resistance:
The titanium addition in grade 321 prevents chromium carbide precipitation during welding and high-temperature exposure, offering excellent resistance to intergranular corrosion.
3. Seamless Construction:
The absence of welds ensures uniform strength and reliability, making these tubes suitable for critical applications under high pressure or stress.
4. Good Mechanical Strength:
TP321 provides high tensile strength and toughness, making it durable under extreme operating conditions.
5. Ease of Fabrication:
TP321 stainless steel is easy to form, weld, and machine, making it convenient for manufacturing and custom applications.
Chemical Composition:
| Grade | C | Cr | Ni | Ti | Mn | Si | P | S | Fe |
| Typical for TP321 | ≤ 0.08% | 17.0–19.0% | 9.0–12.0% | 5x(C+N) minimum, ≤ 0.7% | ≤ 2.0% | ≤ 0.75% | ≤ 0.045% | ≤ 0.03% | Balance |
Mechanical Properties:
| Grade | Yield Strength | Tensile Strength | Elongation |
| ASME SA269 TP321 | ≥ 205 MPa (30 ksi) | ≥ 515 MPa (75 ksi) | ≥ 35% |
Common Applications:
· Heat Exchangers: Used in power plants, refineries, and chemical industries.
· Boilers and Superheaters: Withstands high temperatures and pressure in thermal systems.
· Aerospace and Automotive: Suitable for exhaust systems and components requiring high-temperature resistance.
· Chemical Processing Equipment: Ideal for corrosive environments involving organic and inorganic chemicals.
· Food and Beverage Industry: Safe for use in sanitary applications due to its hygienic properties.
