The ASME SA213 TP321H specification covers seamless ferritic and austenitic stainless steel boiler, superheater, and heat-exchanger tubes. TP321H is a high carbon version of TP321 stainless steel, offering enhanced creep resistance and superior high-temperature strength.
These tubes are engineered for demanding high-temperature and high-pressure applications including boilers, superheaters, and heat exchangers in power plants, chemical processing facilities, and industrial environments requiring exceptional corrosion and heat resistance.
The TP321H grade features increased carbon content and titanium stabilization, ensuring structural stability at temperatures up to 900℃, making it ideal for extreme operating conditions.
Outer Diameter: 31.75mm to 165.2mm
