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.
