ASME SA213 TP321H Stainless Steel Boiler Tube, For Super heater or High Temperature Application
Yuhong group ASME SA213 TP321H is a specification for seamless ferritic and austenitic stainless steel boiler, superheater, and heat-exchanger tubes. TP321H is a high carbon version of TP321 stainless steel, which provides improved creep resistance and high-temperature strength.
These tubes are commonly used in high-temperature and high-pressure applications such as boilers, superheaters, and heat exchangers in power plants, chemical processing plants, and other industrial facilities. They are designed to withstand high temperatures and pressures, making them suitable for use in demanding environments where corrosion resistance and heat resistance are important.
TP321H has high carbon content, also has Ti, so the grade is more stable and can support high temperature application , ASME SA213 TP321H application in the temperateure up to 900℃.
Overall, ASME SA213 TP321H boiler tubes are ideal for applications where high-temperature strength and corrosion resistance are required, making them a reliable choice for various industrial processes.
