Sanitary Seamless Tube ASTM A270 TP316L 1.4404 Bright Annealed

Product Description:

ASME SA269 TP304 1.4301 Austenitic Seamless Bright Annealed Tube

Advantages:

The ASME SA269 TP304 Bright Annealed Tubes can perform well in caustic solutions where chloride and fluoride are absent. They also have excellent forming and welding characteristics and show a great performance in corrosive environments. The seamless tube can also withstand higher pressure.

The ASME SA269 TP304 is an austenitic grade of steel that covers standard seamless and welded configurations. The ASME SA269 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.

ASME SA269 TP304 Stainless Steel Tubing has a density of 8g/cm³ with a melting point of 1400 degrees C. These tubes has excellent mechanical properties and can work well in different pressures and temperatures.
