321 stainless steel plate aadvantage

Uses include aircraft engine components, chemical kilns, exhaust systems and stack liners, flash boilers and welded equipment.321 stainless steel coil and sheet is part of the austenitic family of stainless steel. 321 is basically a 321 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 900 degrees Celsius where 321 is normally used up to 500 degrees Celsius. Grade 321 has excellent forming and welding characteristics. It does not polish well so would not be used for decorative applications. 

321 stainless steel coil description

Type 321 contains a titanium addition of at least five times the carbon content to overcome the sensitizing tendency during welding. Its corrosion resistance is similar to Type 304 but 321 performs better in the 800°-1650°F sensitization range. In Type 321, the oxide or carbonitride of titanium may develop minute black or dark gray inclusions. When the metal is ground or buffed these inclusions may appear and destroy surface appearance, although it will not damage the utility or workability of the metal. Resistance to abrasion is favorable.
