PRODUCT DESCRIPTION

ASTM A312 TP321H is a standard specification for seamless, straight-seam welded, and cold-worked welded austenitic stainless-steel pipes for high-temperature and general corrosive service. TP321H is a high carbon version of TP321 and is used in high-temperature applications as it is strengthened through the addition of titanium. Usually, the ASTM A312 321H seamless pipes are used in chemical processing plants, oil refineries, food processing equipment, and in power generation facilities.
