Heat Exchanger Tube ASTM A269 TP321 SMLS Tube

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.
