321 Stainless Steel Data Sheet

This grade is not sensitive to intergranular corrosion after heating within the carbide precipitation range of 425 850 c.

321 stainless steel data sheet.

321 is the grade of choice for applications in the temperature. The ati technical data sheet on ati 304 may be consulted for an indication of resistance to corrosive media. Type 321 is a stabilized austenitic stainless steel similar to type 304 but with titanium addition used in applications involving continuous or intermittent service at 800 1500 o f 427 816 o c. This alloy contains chromium nickel and titanium.

Fabrication data alloy 321 can be easily welded and processed by standard shop fabrication practices. This material maintains its corrosion resistance in temperatures up to 1500 f. Foil is often used as a heat treating wrap in temperatures up to 2600 f. The table below provides relevant machining data.

This titanium addition reduces or prevents carbide precipitation during welding and in 800 1500 f 427 816 c service. Type 321 is stabilized against chromium carbide formation by the addition of titanium. Technical data sheet type 321 is a chromium nickel stainless steel and with the addition of titanium type 321 is resistant to intergranular corrosion. It also improves the elevated temperature properties of the alloy.

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. It has phenomenal resistance to intergranular corrosion after presentation to temperatures in the chromium carbide precipitation scope of 800 1500 f 427 816 c. Weldable 321 stainless steel the titanium content of 321 stainless steel preserves corrosion resistance around weld points. The alloy maintains oxidation to.

Hot forming working temperatures of 2100 2300 f 1149 1260 c are. It is used principally for applications involving welding or sustained elevated temperature operations. 321 stainless steel sheet 321 is non heat treatable and non magnetic in the annealed condition. Ati 321 ati 347 and ati 348 alloys offer similar resistance to general overall corrosion as the unstabilized chromium nickel ati 304 stainless.
