ASTM A268 TP405 TP409 TP410 TP430 TP403Ti Pickled Annealed Heat Exchanger

If you are looking for heat exchanger tubes that combine durability, thermal efficiency, and corrosion resistance, Gnee offers a full range of ferritic stainless steel tubes that meet ASTM A268 standards, and can also be customized to meet your project requirements.ASTM A268 is the standard specification for ferritic stainless steel tubes used in general corrosion-resistant and high-temperature applications. Grades such as TP405, TP409, TP410, TP430, and TP439Ti are widely used in heat exchangers, condensers, boilers, and exhaust systems where both oxidation resistance and mechanical strength are critical.

These tubes are typically pickled and annealed to improve surface finish, corrosion resistance, and ductility, ensuring stable performance under continuous thermal cycling and corrosive media exposure.
