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 apart from other similar grades.
321 stainless steel plates are part of the austenitic family of stainless steel. 321 is basically a 304 grade containing a stabilizer of titanium. Type 321 is a good choice for applications where heat is an issue. 321 can be used in applications up to 900C where 304 is normally used up to 500C.
321 is a titanium stabilised chromium-nickel austenitic stainless steel with good strength and excellent corrosion resistance, as supplied in the annealed condition with a typical brinell hardness of 175.Characterised by high corrosion resistance in general atmospheric corrosive environments it exhibits excellent resistance to most oxidizing agents, general foodstuffs, sterilizing solutions buy sus 321 steel use
General Properties. Alloy 321 (UNS S32100) is a titanium stabilized austenitic stainless steel with good general corrosion resistance. It has excellent resistance to intergranular corrosion after exposure to temperatures in the chromium carbide precipitation range of 800 1500F (427 816C).
Corrosion Resistance. Alloy 321 stainless steel plate exhibits good general corrosion resistance that is comparable to 304. It was developed for use in the chromium carbide precipitation range of 1800 1500F (427 816C) where un-stabilized alloys such as 304 are subject to intergranular attack.
Grades 321 and 347 are the basic austenitic 18/8 steel (Grade 304) stabilised 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.
While Type 321 continues to be employed for prolonged service in th4e 800 to 1500 F (427 to 816 C) temperature range, Type 304L has supplanted this stabilized grade for applications involving only welding or short time heating. Type 321 stainless steel s also advantageous for high temperature service because of its good mechanical properties.
To be a true stabilized grade the 321 steel has to have Titanium (Ti) content at least 5 times than its Carbon (C) content. Reduced risk of corrosion in the HAZ is the main advantage of 321. Fatigue strength. In dynamic applications, fatigue strength is also important to consider. And in this respect 321 SS has a slight advantage over 304 SS.
Could anyone advise if FCAW electrode E308LT-1 can be used for the welding of 321 to 321 stainless steel plates. The code to be used shall be in accordance to ASME IX.
321 is non-heat treatable and non-magnetic in the annealed condition. This alloy contains chromium, nickel, and titanium. It is used principally for applications involving welding or sustained elevated temperature operations
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.

The key feature of 321 Stainless Steel is its resistance to intergranular corrosion. 321 Stainless Steel also has low risk of weld decay due to addition of Titanium. Type 321 Stainless steel is similar to Type 304 Stainless Steel, however, it contains a Titanium addition of at least five times the carbon content.
The 321 stainless steel pipe tube is a versatile stainless steel tube that is widely used to make equipment and parts that require good overall performance (corrosion resistance and molding). The 321 stainless steel pipe tube is the most widely used stainless steel, heat resistant steel.
We are fabricating a tube bundle with SS 321 weld overlay on tubesheet and SS 304 tubes. The recomended wire is of ER-308 in welding standards. My question is that what if I use ER-321 wire instead of ER-308. Is there any recomendations for this or ER-308 is only recomended due to its lower cost and ER-321 can also be used.
It can improve the aqueous corrosion resistance of welds made in higher carbon grades. Actually, 316Ti is a derivative of 316 in the same way that 321 is related to 304. In fact, 321 is the titanium stabilized version of 304, but while 321 is common in the petrochemical and aerospace industries, 316Ti is not.
