- The material 321 is an austenitic stainless steel with a titanium alloy, which stabilizes the metal against chromium carbide formation. For this reason, 321 can be welded with excellent resistance to intergranular corrosion. The material is also known by the designation EN 1.4541 and the material number X6CrNiTi18-10.

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...

321 Stainless Steel: Composition, Properties. 321 stainless steel is based on Cr-Ni-Ti Austenitic stainless steel, and it is similar to 304 stainless steel, but with better resistance to intergranular corrosion resistance due to the addition of titanium element, and high temperature strength.
Jan 10, 2023 · 321 stainless steel is a type of Inconel sheet that has excellent mechanical properties. It has great formability, weldability, and corrosion resistance compared to typical alloys. This unique alloy can withstand harsh temperatures up to 1500°F due to its high nickel and chromium content.
Mar 17, 2023 · What is 321 Stainless Steel? 321 is also called or known as UNS S32100. It is a non-magnetic and stabilized austenitic alloy or SS. Other identifiable names of 321 SS include: AMS5510. AMS5645. 321 Stainless Steel Rods. Advantages of 321 Stainless Steel? It is non-magnetic. 321 SS provides you with the best resistance to stress corrosion cracking.
Oct 23, 2001 · Grades 321 and 347 are the basic austenitic 18/8 steel (Grade 304) stabilized by Titanium (321) or Niobium (347) additions. These grades are used because they are not sensitive to intergranular corrosion after heating within the carbide precipitation range of 425-850 °C. Grade 321 is the grade of choice for applications in the temperature ...
