ASTM A269 TP304 Stainless Steel Seamless Tubes for Heat Exchangers
The ASTM A269 TP304 is an austenitic grade of steel that covers standard seamless and welded configurations. The ASTM A269 TP304 Tube is designed with a superior composition of nickel and chromium with other constituting alloys， giving these tubes enhanced resistance against corrosive and oxidative media. ASTM A269 Tp304 Stainless Steel Tubing has a density of 8 g/cm3 with a melting point of 1400 degrees C. These tubes has excellent mechanical properties and can work well in different pressures and temperatures.
