One of the reasons for the development of 321 grade of stainless steel was because of its excellent resistance to intergranular corrosion when exposed to a temperature range of 427° C to 816° C during chromium precipitation. The addition of titanium in the alloy of 321 Stainless Steel Fasteners is the reason it is stabilized against chromium carbide formation.

- Application of SS 321 Fasteners
Apart from being resistant to intergranular corrosion, SS 321 Socket Cap Screw the is well suited for high temperature applications because the fasteners retain their good mechanical properties like high creep and stress rupture strength even at elevated temperatures.While 304L grade stainless steel fasteners are limited to temperature applications up to 426° C, 321 grade stainless steels can be used up to a maximum of 816° C.
The corrosion resistance for both SS 321 Bolts and 304 are similar in terms of general and localized corrosion. Although prolonged heating of 321 grade at chromium precipitation range may affect the general resistance of the alloy in corrosive media. Similar to ss 304, Stainless Steel 321 Bolts are susceptible to stress related corrosion cracking when exposed to environments containing halide compounds.
The resistance of the alloy of Stainless Steel 321 Nuts is similar to fasteners of the 304 grade or Type 304L, in the presence of chloride ion.In applications where there are crevices present, 100 ppm chloride in aqueous environments is considered to be the limit for both the stabilized alloys like 321 SS Stud Bolt as well as unsterilized alloys. Levels of chloride ion higher than 100 ppm or parts per million can cause either or both crevice corrosion and pitting. In case of applications, where the content of chloride level is high, it is better that stainless steel grades like 316 or higher molybdenum content stainless steel grades be considered.
The SS 321 Screws are not recommended for exposure to brine or salt water. Hence they are not to be used in marine
