A213 TP304 Stainless Steel Tube Description
ASTM A213 TP304 is a standard for austenitic stainless steel seamless tubes and pipes developed by the American Society for Testing and Materials (ASTM) for use in boilers, superheaters, heat exchangers, and other high-temperature, high-pressure equipment. Core properties include high-temperature and high-pressure equipment, such as superheaters, heat exchangers, and others.
Production Process
Seamless Tube Manufacturing:
Hot rolled/cold rolled: hot rolled billets are shaped by piercing or cold drawing processes to ensure that there are no welding defects.
Solution Treatment: Heated to 1010-1150°C and then cooled quickly to eliminate stress and enhance corrosion resistance.
Surface Treatment: The internal and external walls are polished to meet sanitary standards, for example, in the medical and food industries.
