ASTM A376 TP321H Stainless Steel Tube For Superheater and Reheater Tubes in High-Pressure Boilers
Specifications
ASTM A376 TP321H is the high-carbon version of the titanium-stabilized TP321 grade, specified for seamless austenitic steel tubes in high-temperature service. The "H" designation ensures a controlled carbon content (0.04-0.10%) to provide enhanced high-temperature creep strength and stress rupture properties compared to standard TP321.
ASTM A376 TP321H tubing is engineered and applied specifically for high-temperature, high-pressure service where long-term creep strength and resistance to sensitization are the primary design considerations.
