With the exploration and innovation of company people, gradually formed four major advantageous products: steel plate, steel pipe, stainless steel, special steel.
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.
Type 321 is a stabilized stainless steel which offers as its main advantage 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). Type 321 is stabilized against chromium carbide formation by the addition of titanium.
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.
Three types of stainless steel (AISI 304, AISI 316, AISI 321) with different chemical compositions were selected (Table 1). In spite of inconsiderable differences in the content of alloy additions, they are characterized by different corrosion resistance and are used in various applications. Stainless steel
Alloy 321 (UNS S32100) is stabilized stainless steel which offers as its main advantage an excellent resistance to intergranular corrosion following exposure to temperatures in the chromium carbide precipitation range from 800 to 1500F (427 to 816C).Alloy 321 stainless steelis stabilized against chromium carbide formation by the addition of titanium.
Stainless 321 is a chromium-nickel steel which was developed with improved intergranular-corrosion resistance. Stainless 321 is resistant to atmospheric corrosion, sterilizing solutions, many organic chemicals, and a wide variety of inorganic chemicals.
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 sus 321 steel use
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.
321 Stainless Steel. A Chromium (17-20%), Nickel (9-13%), Iron Alloy modified with the addition of titanium to prevent carbide precipitation and resulting intergranular corrosion that can take place in certain mediums when operating in the 800-1200F (427-649C) temperature range.
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.
The stainless steel tube is equivalent to the 0Cr19Ni9 (0Cr18Ni9) stainless steel pipe in our country. 304 contains 18% of chromium and 8% nickel. The 321 stainless steel pipe tube is the most widely used for stainless steel, the equipment for food, general chemical equipment, and the atomic energy industry.
321 is an austenitic stainless steel that is melted as AOD melt type. This is a stabalized version of 304 stainless to help improve intergranular corrosion resistance. This alloy is similar to 347 stainless except uses titanium to stabilize the carbon instead of niobium.
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).

321 Stainless Steel Grading. Grade 321 stainless steel can be scrapped at most scrap metal yards for cash. This grade of stainless steel is commonly used for aircraft exhaust manifolds, furnace parts and spiral welded tubes for burner pipes and flues so the 321 Stainless Steel Scrap Prices can vary.
JIS G4403 SUS321--- Austenitic stainless steel. Austenitic stainless steel JIS G4403 SUS321 main features and application. JIS G4403 SUS321 stainless steel is similar to Type SUS304 stainless steel, however, it contains a Titanium addition of at least five times the carbon content.
Use 309L (including ER309LSi) when joining mild steel or low alloy steel to stainless steels, for joining dissimilar stainless steels such as 409 to itself or to 304L stainless, as well as for joining 309 base metal. CG-12 is the cast equivalent of 309.
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
