Alloy 321 is
stabilized against chromium carbide formation by the addition of titanium.

offer as their main
advantage an excellent resistance to intergranular corrosion following exposure to temperatures
in the chromium carbide precipitation range from 800 to 1500°F (427 to 816°C), also advantageous for high temperature service because
of their good mechanical properties.
