AISI 321 stainless steel (SS321) is basically type 304with 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 ru...
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.
The tables below list AISI 321 stainless steel properties, including physical and mechanical properties.
Recommended annealing temperature for TP321 and 321 wrought stainless steel: 1040 °C (1900 °F); Minimum 1095 °C (2000 °F) for cold-worked 321H and 1050 °C (1095 °F) for hot-finished 321HStress-relieving treatmentsTypical forging temperature: 925-1260 °C (1700-2300 °F).SS321 and TP321 has excellent weldability, no preheating is required. The filling material needs to have similar composition but higher alloy content. Liquation cracking in heat affected zone: low energy input. Fine grain size. Ferrite ≥ 5%. Recommended filler metals are SS 321, 347, and 348. Electrode is E347 or E308L [service temperature < 370 °C...
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 vehicl...
AISI TP321, 321H and 321 stainless steel equivalent to European EN (German DIN EN, British BSI EN, France NF EN), ISO, Japanese JIS and Chinese GB standard (for reference). Related material: AISI 316, 316L stainless steel
321 Stainless Aerospace Tubing. 321 stainless aerospace tubing is made from an austenitic stainless steel offering an excellent resistance to intergranular corrosion following exposure to temperatures in the chromium carbide precipitation range from 800 to 1500°F (427 to 816°C). Alloy 321 stainless steel is resistant to chromium carbide ...

321 Stainless Steel. This is a standard austenitic 18/8 stainless steel grade, (304), but stabilized by Titanium. The titanium within means the stainless steel is intergranular corrosion resistant after heating, (between 425-900 degrees Celsius). Remarkably high strength as well as scaling resistance and phase stability set 321 Stainless Steel ...
Nov 23, 2020 · The most common of these stabilized grades are types 321 and 347. Type 321 contains a minimum of 5 × (C% + N%) titanium, and type 347 a minimum of 8 × C% niobium. Nitrogen must be considered when titanium is used as a stabilizer, not because the precipitation of chromium nitride is a problem in austenitic steels, but because titanium nitride ...
Jan 10, 2023 · 321 Stainless Steel Composition. UNS S32100 composition is an ideal choice for Inconel sheet applications. It has excellent high-temperature strength, good corrosion resistance, and forming ability, as well as great weldability. Other benefits of its composition include high resistance to scaling from heating in high-temperature environments ...
