ASTM A249 TP321 Stainless Steel Welded Bright Annealed Tube, Heat Exchanger and Condenser Application
A high-performance welded austenitic stainless steel tube designed for demanding applications. This product, made from TP321 (S32100) material and finished with a Bright Annealed (BA) treatment, perfectly combines exceptional resistance to intergranular corrosion, superior high-temperature strength, and an unparalleled smooth surface finish. It is the ideal choice for heat exchangers, condensers, and hygienic applications in industries such as food and pharmaceutical.

2. Key Adventages
Stabilized with Titanium (Ti) to effectively prevent intergranular corrosion in the carbide precipitation sensitization range (450-850°C). Ideal for components that cannot be solution annealed after welding.
Superior High-Temperature Performance
It maintains good oxidation resistance, creep resistance and long-term strength even at high temperatures, making it a reliable choice for boiler, superheater and heat exchanger tubes.
Annealed in a controlled atmosphere furnace resulting in a smooth, bright, and scale-free surface. This finish is easy to clean, reduces the risk of product contamination, and enhances corrosion resistance.
Manufactured with advanced welding and cold-reduction processes ensuring tight dimensional tolerances, uniform wall thickness, and excellent concentricity.
Good resistance to a wide range of organic and inorganic chemicals, as well as oxidizing media.
