ASTM A213 TP321
ASME SA213 TP321 Austenite Seamless Heat Exchanger Tube Adaptable Heat Exchange Equipment
ASTM A213 TP321 is a seamless austenitic stainless steel tube stabilized with titanium.
Its core design goal is similar to TP347H, which can solve the "sensitization" problem of austenitic stainless steel and improve its resistance to intergranular corrosion when operating in the high-temperature range (450-850°C).
