ASTM A249 TP304， 1.4301 Bright Annealed Stainless Steel Welded Tube For Heat Exchanger
The ASTM A249 TP304 Tube is designed with a superior composition consisting of nickel and chromium with other alloy elements. The content embedded within these tubes makes them have excellent resistance to reductive and corrosive media. ASTM A249 TP304 stainless steel welded tube has good properties for boiler， super heater， heat exchanger and condenser. It particularly provides good corrosion resistance and high strength. 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.
