TP 321 Steel Pipe is a stable stainless steel whose primary
advantage is its excellent resistance to intergranular corrosion
after exposure to the chromium carbide precipitation temperature
range of 800°F to 1500°F (427°C to 816°C). Alloy 321 stainless
steel pipe is stabilized by the addition of titanium to form
chromium carbide.
321 321H stainless steel tube is a titanium-stabilized version of
304 for specific applications within the sensitization temperature
range. Its resistance to sensitization and higher strength at
elevated temperatures make it suitable for applications where 304
will sensitize or where the heat strength of 304L is insufficient.
Weld corrosion and intergranular corrosion will not occur when
exposed to mildly corrosive environments. However, welding 321
should never be used in highly oxidizing environments as it is
susceptible to "knife line" erosion.
However, in operating temperature environments above 500°C, 321 is
the better choice and therefore has its own advantages. Alloy 321
stainless steel pipe is also beneficial for high temperature use
due to its good mechanical properties. Alloy 321 stainless steel
has higher creep and stress rupture properties than Alloy 304, and
Alloy 304L in particular may also be considered for sensitive and
intergranular corrosion problems.
