C → Reduces intergranular corrosion risk
Cr → Oxidation & corrosion resistance
Ni → Austenitic structure stability
Ti→Prevents carbide precipitation (sensitization) during welding or high-temperature exposure (450–850°C)

Austenitic Structure: Provides excellent toughness and high-temperature strength.
TP321 superior to 304/304L: Better resistance to intergranular corrosion in welded applications.
Key Features Suitable For Heat Exchangers
Material of ASTM A213 TP321 is a titanium-stabilized austenitic stainless steel specifically designed for high-temperature and corrosive environments. Its properties make it an excellent choice for bundle tubes used in heat exchangers, boilers, and other critical applications
TP321 has high-temperature resistance,performs well in prolonged high-heat conditions (e.g., superheaters, reformer tubes)
Common Applications in Power Plants
| Shell & Tube Heat Exchangers,Boiler Superheaters & Condensers |
| Petrochemical & Refinery Furnaces |
| Power Generation Systems |
| Food & Pharmaceutical Processing |
