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.
