Key Features & Benefits 0f ASTM A249 TP321 Stainless Steel Welded Tubes
Our ASTM A249 TP321 stainless steel welded tubes offer a range of benefits, making them a preferred choice for critical applications:
Excellent Corrosion Resistance: TP321 stainless steel exhibits outstanding resistance to general corrosion, pitting, and crevice corrosion in a wide range of corrosive media.
Stabilized Against Carbide Precipitation: The addition of titanium stabilizes the steel against the formation of detrimental chromium carbides at grain boundaries during exposure in the temperature range of 800-1500°F (427-816°C). This makes it suitable for high-temperature service.
High Strength at Elevated Temperatures: TP321 maintains good strength and creep resistance at elevated temperatures compared to other austenitic stainless steels like 304.
Good Weldability: While stabilized, TP321 can be readily welded by most common welding processes. Post-weld annealing is generally not required for stabilizing the material.
Versatile Applications: Ideal for use in heat exchangers, superheaters, boiler tubes, pressure vessels, exhaust systems, and other high-temperature equipment.
Manufactured to ASTM A249 Standards: Our tubes are manufactured in strict accordance with the ASTM A249 specification, covering welded austenitic steel boiler, superheater, heat-exchanger, and condenser tubes. This ensures dimensional accuracy and material integrity.
