Product Description

TP321 is a titanium-stabilized austenitic stainless steel offering excellent resistance to intergranular corrosion following exposure to temperatures between 427°C to 816°C (800°F to 1500°F). This alloy is particularly suitable for high-temperature applications requiring oxidation and corrosion resistance.

When used in ASTM A249 TP321 Wound Fin Tubes, it provides robust performance and efficient heat transfer for applications in power generation, industrial boilers, chemical processing, and aerospace industries.

Key Features
  • Enhanced Heat Transfer: Fins significantly increase surface area for improved heat transfer rates
  • Corrosion Resistance: TP321 provides excellent resistance to oxidation and intergranular corrosion
  • Mechanical Bonding: Wound fin design ensures secure bond between fins and base tube
  • High Thermal Conductivity: Aluminum fins ensure efficient heat exchanger performance
  • Durable Construction: TP321 base tube withstands mechanical stress at high temperatures
Applications
Heat Exchangers

Shell and Tube Heat Exchangers for chemical/petrochemical industries and Air-Cooled Heat Exchangers for industrial/HVAC applications.

Boilers and Superheaters

Used in steam boilers and superheaters in power generation plants and industrial boilers requiring high temperature/pressure resistance.

Chemical Processing

Ideal for heat exchangers and condensers in chemical plants and petrochemical refineries handling corrosive substances.
