Alloy 321 is stabilized against chromium carbide formation by the addition of titanium.
offer as their mainadvantage an excellent resistance to intergranular corrosion following exposure to temperaturesin the chromium carbide precipitation range from 800 to 1500°F (427 to 816°C), also advantageous for high temperature service becauseof their good mechanical properties.
