Stainless Steel 321 ASTM A213 A249 A269 A312 A376 UNS S32100 Seamless Welded Pipe Tube, Stainless Steel 321 Pipe/ Tube, 321 Stainless Steel Seamless Tubing, AISI 321 ERW Pipe, EN 1.4541 Tubing and UNS S32100 Stainless Steel Pipe, 321 UNS S32100 ERW Pipe.

Stainless Steel 321 ASTM A213 A249 A269 A312 A376 UNS S32100 Seamless Welded Pipe Tube:

Designed with a density of 8.27 g/cm3, the Stainless Steel 321 Seamless Tube exhibits outstanding strength as compared to the seamless pipes. These UNS S32100 Seamless Welded Pipe Tubes can be formed in square, round, rectangular cross sections allowing them to adapt to different applications.

 

The robust 321 Stainless Steel Tubing can be either hot or cold rolled and further heat treated. These UNS S32100 Seamless Welded Pipe Tubes are generally annealed at temperatures around 1605 degrees F, followed by a water quenching process. This gives the tubing enhanced resistance to corrosive media. EN 1.4541 Tubing can be custom designed in an array of shapes and sizes. This tubing is commonly seen in expansion joints, heat exchangers, furnace parts, aircraft exhaust manifolds, bellows, etc.

 

Grade 321 is an austenitic alloy, which is stabilized with the help of titanium. The Stainless Steel 321 Pipe Tube provides excellent corrosion resistance properties and acts as a sterilizing agent.
