321 Stainless Steel Seamless Pipe
Short Description:
ASTM TP321 SEAMLESS PIPE :
321 stainless steel seamless pipe is a high-performance material widely used in high-temperature environments. 321 stainless steel is based on the 18Cr-8Ni composition with the addition of titanium to enhance its resistance to intergranular corrosion.321 stainless steel seamless pipe performs excellently in high-temperature environments and can be continuously used in the temperature range of 800-1500°F (427-816°C), with a maximum temperature of 1700°F (927°C).Due to the addition of titanium, 321 stainless steel has good resistance to intergranular corrosion, making it suitable for environments where intergranular corrosion might occur under high-temperature conditions.321 stainless steel has high yield strength and tensile strength, along with good ductility and toughness.321 stainless steel can be welded using conventional welding methods, but post-weld annealing may be necessary to restore its corrosion resistance.
