ASTM A249 TP321 WLD Heat Exchanger Tube, for Heat Transfer

Heat Exchanger Tubes made from ASTM A249 TP321 are a preferred choice for various industrial heat transfer applications due to their excellent corrosion resistance, high-temperature strength, and durability.

Material Description:

ASTM A249 TP321 is a stainless steel alloy that belongs to the 300-series (austenitic stainless steel). It is stabilized with titanium (Ti), which improves its resistance to intergranular corrosion, particularly in high-temperature environments. This stabilization makes TP321 ideal for welded applications and heat exchanger systems.

Key Features:

1. High-Temperature Resistance:

TP321 can withstand temperatures up to 870°C (1600°F), making it suitable for high-pressure and high-temperature operations.

2. Corrosion Resistance:
Excellent resistance to oxidation, stress corrosion cracking, and intergranular corrosion.

3. Good Weldability:
The titanium stabilization minimizes carbide precipitation during welding, avoiding corrosion at weld joints.

4. Durability:
High strength and resistance to thermal fatigue ensure a long service life.
