ASTM A269 TP304 Stainless Steel Seamless Tube Pickled Annealed for Heat Exchanger and General Service

ASTM A269 is one of the most widely used standards for austenitic stainless steel tubes, typically covering smaller outer diameters and relatively thin wall thicknesses from capillaries. For applications such as high-temperature and high-pressure boilers, superheaters, and heat exchangers, ASTM A213 TP304 should be preferred. This standard has stricter requirements for the chemical composition, mechanical properties (especially high-temperature performance), and non-destructive testing of seamless tubes, while ASTM A269 focuses more on "general service" conditions.

Why Choose ASTM A269 TP304 Stainless Steel Seamless Tube?

Versatility and Maturity: TP304 is one of the most commonly used and proven stainless steel grades, with extensive performance data and application experience.
Excellent Overall Performance: ASTM A269 TP304 seamless stainless steel tube offers an excellent balance of corrosion resistance, strength, toughness, formability, and weldability, making it suitable for a wide range of applications.
Good Processability: ASTM A269 TP304 seamless stainless steel tube is easy to bend, form, weld, and install.
High Cleanliness: ASTM A269 TP304 seamless stainless steel tube has a smooth inner wall that resists media retention and is easy to clean and sterilize, making it ideal for the food and pharmaceutical industries.
Advantages of Seamless Construction: No longitudinal welds provide greater structural integrity, generally better pressure-bearing capacity, and a more uniform internal and external surface, reducing the risk of leaks.
