Stainless Steel 321 Pipe

Different between SS 321 Seamless/Welded/ERW Tube
Tubes in the SS 321 grade are commonly manufactured in seamless, welded, or erw configurations. All these configurations can be separated based on key features.

  • A seamless tube is produced by passing hot steel billets through an extruding metal and shaping it precisely. This standard are the strongest grade used in manufacturing tubes in the SS 321 grade.
  • A welded tube is manufactured by welding pieces of sheet or strips either longitudinally or horizontally.
  • Erw pipes are produced by cold rolling flat strips and then passing them through a series of dies to get a longitudinal seam.

What is ASTM A312 TP 321 Round Pipe
ASTM A312 Tp 321 round pipe covers standard specifications of seamless or welded austenitic stainless steel pipes. The circular cross-section pipes are designed to perform well in high temperatures and different corrosive media.

Different between SS 321 vs ss321h Pipe
SS 321 and ss321h pipes are designed with nearly identical characteristics and features. The major difference between both these piping components is the presence of carbon content. A SS 321h has a carbon content of 0.04% up to 0.10%. Themaximum carbon content in the SS 321 pipe grade is 0.08%.

What is the difference between ASTM A312 TP 321 and ASME SA 312 TP 321
ASTM and ASME are important standards that are used in manufacturing piping modules in the 321 grade. Both these grades can be distinguished based on certain features.

  • ASTM A312 TP 321 grade covers structural qualities and different features of piping items. ASME SA 312 TP 321 covers standard design codes for a range of pressure-rated applications.

Stainless Steel 321 Cold Rolled and Hot Rolled Plate
Stainless steel 321 plate is an austenitic grade that can be produced either by hot or cold rolling procedures. In a hot rolling process, the metal is processed at high temperatures followed by cold rolling. Here the plates are rolled at room temperature, giving them good tolerances and strengths.

How Do You Anneal 321 Stainless Steel Pipe
The SS321 pipes are heated at temperatures between 950 to 1120 degrees C, followed by rapid cooling. The pipes can be stabilized with heat of 870-900 degrees C for 1 hour. The metal is stress-relieved for 1-2 hours at 700 degrees C followed by air cooling.
