ASTM A312 TP321H Stainless Steel Seamless Pipe For Petrochemical

ASTM A312 TP321H is a seamless austenitic stainless steel tube designed for high-temperature and corrosive environments. Due to its excellent corrosion resistance and mechanical strength at high temperatures, it is suitable for the petrochemical industry. SS 321H is a stabilized austenitic stainless steel, similar to 321 stainless steel, but with the addition of titanium. Titanium reduces or prevents carbide precipitation during welding and at high temperatures of 800–1500 °F (427–816 °C). It also improves the alloy's high-temperature properties. 321H stainless steel tube is non-magnetic and heat-resistant, allowing for continuous use at high temperatures.
