AISI 321 Stainless Steel (SS321), 321H, TP321
AISI 321 stainless steel (SS321) is basically type 304 with the
addition of titanium (Ti), which stabilizes carbides against
sensitization to prevent intergranular precipitation of chromium
carbide when the steel is heated to a temperature within the
sensitization range (such as during welding). 321H is to obtain the
best creep strength and creep rupture strength. TP321 stainless
steel is for seamless, welded, and heavily cold worked pipes.

The following tables and lists give grade 321 stainless steel
datasheet and specification including chemical composition,
physical properties and mechanical properties, machinability, heat
treatment, welding, etc.

Applications
Type 321, 321H and TP321 can be used in places where solution
treatment after welding is not possible, such as steam lines and
superheater pipes and exhaust systems in reciprocating engines and
gas turbines with temperatures ranging from 425 to 870 °C (800 to
1600 °F). And fuel injection lines and hydraulic systems for
aircraft and aerospace vehicles.
