ASTM A213 TP321 Heat Exchanger Stainless Steel Seamless Tubes
ASME SA213/ASTM A213 This specification covers seamless ferritic and austenitic steel boiler, superheater, and heat-exchanger tubes, designated Grades T5, TP304, TP321, etc.In a heat exchanger, TP321 tubes play a crucial role due to their high-temperature resistance, corrosion resistance, and stability.

Advantages
Heat Transfer Efficiency
TP321 tubes facilitate efficient heat exchange between two fluids (liquid/liquid, gas/liquid, or gas/gas) due to their good thermal conductivity.Even under high thermal stress, they maintain structural integrity .
Corrosion & Oxidation Resistance
Titanium-stabilized (321 SS) composition prevents intergranular corrosion (sensitization) in high-temperature environments (up to 900°C / 1650°F).
Due to the resistant to acidic, caustic, and chloride-rich environments, making them ideal for chemical, petrochemical, and refinery applications.
High-Temperature Strength
TP321 retains mechanical strength at elevated temperatures, preventing deformation or failure in boilers, superheaters, and exhaust systems.
Resistance to Stress Corrosion Cracking (SCC)
The addition of titanium (Ti) minimizes carbide precipitation at grain boundaries, reducing the risk of cracking in welded or high-stress zones.
Applications
Oil & Gas : Used in heat recovery systems, condensers, and furnace tubes.
Aerospace & Automotive: Used in exhaust systems and thermal management.
Power Plants: Common in steam boilers, superheaters, and heat exchangers.
Chemical Processing: Handles corrosive fluids and high-pressure steam.
