321 Stainless Steel Technical Data Sheet - metal shims
The annealing temperature range for Type 321 is 1800 to 2000 F (928 to 1093 C). While the primary purpose of annealing is to obtain softness and high ductility, this steel may also be stress relief annealed within the carbide precipitation range 800 to 1500 F (427 to 816 C), without any danger of subsequent intergranular corrosion.
Stainless Steel - Grade 321 (UNS S32100)
321 is similar to 304, but uses titanium as a stabiliser. They differ in that they are resistant to intergranular corrosion after heating to temperatures in the carbide precipitation range. Applications include aircraft exhaust manifolds, furnace parts, heat exchangers, furnace parts etc.

321 - Rolled Alloys, Inc.
321 stainless is a titanium stabilized grade commonly used for service in the 1000-1600F temperature range. For service temperatures up to about 1600F, a stabilizing treatment at 1550-1650F, air cool, may be used to provide optimum resistance to intergranular corrosion and to polythionic acid stress corrosion cracking.

STRESS RELIEVING The lower-carbon-grade 304L can be stress relieved at 450C to 600C for 60 minutes with little danger of sensitization. A lower stress relieving temperature of 400C maximum must be used with 304 SS with longer soaking times. If, however, stress relieving is to be
Grade 321 Stainless Steel Technical Data
Stainless Steel - Grade 321 CS 321 Technical Data . CS 321 is a titanium-stabilised version of CS 304, used in particular applications within the sensitizing temperature range. Its resistance to sensitization, coupled with its higher strength at high temperature makes it suitable in application where CS 304 will become sensitized, or where CS 304L has insufficient hot strength.

We buy 17-4 DH 1150 for NACE and machine it every day with no post machine stress relieve. We have never had any problems. The best thing to do if in doubt is to machine a piece with known mechanical properties, then send it out for testing (without stress relief) and see if the properties change. jferguson
Stress Relief - Heat Treat Doctor.com
Stress relief is a simple heat-treating operation for wire products that depends strongly on the proper selection of temperature and time at temperature for its success. A proper cooling rate is also a surprisingly important factor. So, the next time that your products need stress relief, be sure that your heat treater fully understands what

PWHT of chromium-nickel austenitic stainless steels - TWI
In such circumstances, a lower temperature treatment (eg at around 400C) giving partial stress relief without precipitation of second phases may be preferable. The need for a stress-relief treatment in weldments constructed of austenitic stainless steel has been over-emphasised in the past and has been removed from many standards.
