321 SS Tubing Description
321 Stainless Steel Tubing is a titanium-stabilized austenitic stainless steel with good intergranular corrosion resistance and high temperature strength.Due to the addition of titanium, 321 stainless steel tube has high mechanical strength and creep resistance at high temperatures, suitable for long-term use in high temperature environments.
321 ss tubing has excellent oxidation resistance and corrosion resistance in high temperature environments, especially in the temperature range of 800-1500°F (427-816°C), which can effectively prevent intergranular corrosion.

Type 321 Stainless Steel is an austenitic stainless steel. It has many of the same qualities of Type 304, except for a higher level of titanium and carbon.
Type 321 offers outstanding corrosion and oxidation resistance, as well as excellent toughness even down to cryogenic temperatures. 321 Stainless is resistant to atmospheric corrosion, sterilizing solutions, many organic chemicals, and a wide variety of inorganic chemicals.
