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.
Chemical Composition and Products of 321 Materials in Different Standard
SS 321 stainless steel chemical composition is listed in the following table based on cast analysis.

| TP321H (UNS S32109) | 0.04-0.10 | 1.00 | 2.00 | 0.045 | 0.03 | 17.0-19.0 | 9.0-12.0 | 0.10 | ≥ Ti 4x(C+N), ≤ 0.70 |
Applications of 321 Stainless Steel
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.
