ASTM A249 TP304, 1.4301 Bright Annealed Stainless Steel Welded Tube For Heat Exchanger
ASTM A249 TP304 is a standard specification for welded austenitic steel boiler, superheater, heat-exchanger, and condenser tubes. It specifies the requirements for tubes to be used in high-temperature services. ASTM A 249 TP304 Material offers good corrosion resistance. Due to the titanium content in ASTM A 249 TP304 ERW Tube, it’s immune to precipitation. The titanium content in the ASTM A249 TP304 SS Tube stabilizes the tube structure at 800 degrees C.
