Acid Resistance Bright Annealed ASME SA213 TP304 1.4301 Seamless Tube
Bright Annealed ASME SA213 TP304 1.4301 Seamless Tube Austenitic
ASTM A213 covers seamless ferritic and austenitic steel boiler, superheater, and heat-exchanger tubes.
Bright annealed stainless steel tube is a kind of high precision steel tube material after finishing or cold rolling. Due to the advantages of no oxide layer both inside and outside wall, no leakage under high pressure, high precision, high finish degree, no deformation and flaring, no cracks flattening, precision bright annealed tube is mainly used to produce pneumatic or hydraulic components, such as air cylinder or gas cylinder. It can be seamless tube, and also welded pipe.
Bright Annealed Stainless Steel Tubing Advantages
1. Superior Surface Finish
2. Better Mechanical Property
3. More Precise Dimension
ASTM A213 TP304 is a grade that covers standard heat exchanger or high-pressure tubes that are designed with 304 austenitic stainless steel. The ASTM A213 TP304 Tube is designed with a superior composition consisting of chromium and nickel.
This gives the tubes enhanced resistance against corrosive and oxidative media across an array of stress-induced environments. The grade covers standard seamless, welded, and erw configurations.
