ASTM A213 TP321 Stainless Steel Seamless Tube Corrosion Resistance Low Temperature
Specifications
ASTM A213 TP321 stainless steel seamless tube is a corrosion-resistant, austenitic steel tube stabilized with titanium, designed for high-temperature applications like boilers and heat exchangers. It is manufactured without welds, making it strong and durable, and it offers excellent resistance to intergranular corrosion, especially after welding, and good resistance to scaling and stress rupture at high temperatures (up to about 900°C).
