Alloy 321 (UNS S32100) is a titanium stabilized austenitic stainless steel plate with good corrosion resistance. It has great resistance to intergranular corrosion after exposure to temperatures in the chromium carbide precipitation range of 800 1500°F (427 816°C). Alloy 321 321 stainless steel welding321H Heat Resistant Stainless Steel Plate Welding. Alloy 321 stainless steel plate can be readily welded by most standard processes. A post weld heat treatment is not necessary.

Austenitic (300 Series) Stainless Steel Filler Metals Stainless steel filler metal is 35 times more expensive than carbon steel even small mistakes are expensive Class Description E308 Used for stainless steel types 301, 302, 304L, 321, CF-3 and CF-8 E309 Used for stainless steel types 304, 304L, 309, 309L; often used in welding stainless steel to Austenitic (300 Series) Stainless Steel Filler Metals Stainless steel filler metal is 35 times more expensive than carbon steel even small mistakes are expensive Class Description E308 Used for stainless steel types 301, 302, 304L, 321, CF-3 and CF-8 E309 Used for stainless steel types 304, 304L, 309, 309L; often used in welding stainless steel to
Difference Between 304 304L and 321. 304 stainless steel is low carbon chromium nickel stainless and heat resisting steel somewhat superior to Type 302 in corrosion resistance.. 321 stainless steel is known as stabilized grades of stainless steel, is Chromium nickel steel containing titanium. Recommended for parts fabricated by welding which cannot be subsequently annealed. SS321 AISI 321 Stainless Steel Properties, TP321 321H SS321, AISI 321 Stainless Steel 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 STAINLESS Selector Guide - Welding Products, Wires STAINLESS Filler Metal Selector Guide AISI TYPE NUMBER 442 446 430F 430 FSE 430 431 501 502 416 416 SE 403 405 410 420 414 321 348 347 317 316L 316 314 310 310S 309 309S Stainless Steel - Grade 321 (UNS S32100)
Weld Wire; 321 Stainless Steel Overview. Stainless 321 is a heat resistant, titanium stabilized, austenitic alloy that's commonly used for service in the 1000°-1600°F temperature range. 321 stainless is primarily used in applications that involve continuous and intermittent service temperatures within the carbide precipitation range of 800 Stainless Steel MIG wire, 5 Best and 10 Welding TipsJan 07, 2020 · The Blue Demon 308LSI stainless welding wire should be used with types 304 and type 308, 321, 347 grades of stainless steel. And it is an all position welding wire. Recommended shielding gas:98% Argon and 2% Oxygen for spray transfer with 0.030 diameter size wire. USA 321Stainless Steel Welding Wire Products ER321 is a 19% chromium 9% nickel plus titanium stainless steel filler metal used for TIG welding base metals of similar analysis. The titanium content reduces intergranular chromium carbide precipitation thereby increasing resistance to intergranular corrosion. Welding Forum > 304 321 stainless steel welding 321 Stainless Steel.Feb 03, 2006 · 321 stainless is basically an 18 321 stainless steel welding8 stainless like 304 with a small addition of titanium. 304 has similar corrosion resistance qualities to 321, but 321 has superior mechanical properties at elevated temperatures compared to 304. As nigel points out:321 should be welded using 347 filler wire.
The alternative is to select a steel that is more resistant; the molybdenum bearing grade type 316 is better than 304 or 321. The ferritic stainless steels (Job Knowledge 101) are not susceptible to chloride SCC. This article was written by Gene Mathers. Welding of SS 321 and SS 304 - AWS (welding) Code Issues Feb 23, 2005 · Our standard is ER347 in welding 321 to 304 or mostly 304L. We have had no problems with either base or weld metal with this procedure in a very corrosive service, (HNO3 + Organics @ 120°C). All welding on 321 is with 347 wire 321 stainless steel weldingelectrodes due to metallurgical concerns. Stainless Steels Welding Guide - Lincoln Electricwire. Type 321 is available on a limited basis as solid and cored wire. Two problems are associated with welds in the austenitic stainless steels:1) sensitization of the weld heat affected zone, and 2) hot cracking of weld metal. 3.3.1 SENSITIZATION:Sensitization leads to intergranular corrosion in the heat affected zone as shown in Figure 1 .
