ASTM A213 TP321 Stainless Steel Heat Exchanger Tube For Chemical Industry

ASTM A213 TP321 Stainless Steel Heat Exchanger Tube For Chemical Industry

ASME SA213 outlines the requirements for seamless and welded tubes intended for use in boiler, superheater, and heat exchanger applications. It ensures that the tubes meet stringent industry standards for quality and performance.

TP321 exhibits good tensile strength, ductility, and excellent weldability. The addition of titanium enhances its resistance to high-temperature oxidation and scaling.While the thermal conductivity of TP321 is not as high as that of carbon steels, it is sufficient for effective heat transfer in heat exchanger applications.
