ASTM A249 TP321 SS Welded Heat Exchanger Tube supplier

ASTM A249 TP321 SS is a weldable austenitic stainless steel tube designed for high-temperature applications such as heat exchangers, boilers, and superheaters. The "TP321" designation indicates its composition, which includes titanium as a stabilizing element. Compared to other stainless steel grades, this gives it greater resistance to intergranular corrosion and improves its high-temperature mechanical properties.

We supply high-quality ASTM A249 TP321 stainless steel heat exchange tubes with good machinability, suitable for stamping and cold working. Due to the high chromium content in TP321 heat exchange tubes, they resist high-temperature corrosion and maintain good corrosion resistance. ASTM A249 304 type ERW tubes have a scale-free surface, achieved through bright annealing in a controlled atmosphere. Unless flaring and bending are required, ASME SA 249 TP 304 tubes used in the food industry are typically not heat-treated. ASTM A249 tubing ranges in wall thickness from ⅛ inches inside to 12 inches outside.

ASTM A249 TP321 stainless steel heat exchange tubes offer excellent performance and are suitable for food processing, chemical, and shipbuilding industries, as well as for demanding applications such as automotive parts, components, and heat exchangers.
