What are Stainless Steel 321 Tubes

Stainless steel 321 tubes are the preferred grade for applications requiring temperatures up to around 900 degrees Celsius because they combine high strength, resistance to scaling and phase instability, and resistance to subsequent aqueous corrosion. We sell Grade 321 Stainless Steel Pipes at a reasonable price.

The main advantage of the stabilized stainless steel SS 321 Tubes is their excellent resistance to intergranular corrosion after exposure to temperatures in the chromium carbide precipitation range of 800 to 1500 degrees F. (427 to 816 Degrees C). Stainless Steel 321 Seamless Pipes is a stabilized austenitic stainless steel with at least five times the titanium content of Type 304.

Functions Of Stainless Steel 321 Tubes

Although Stainless Steel 321 Tubes Stainless Steel 321 Welded Pipes resemble Type 304 stainless steel, they include at least five times as much titanium as carbon. As a result of welding or exposure to high temperatures, precipitation of chromium carbide is reduced or eliminated by this addition.

 Stainless Steel 321 Tubing is an excellent choice for applications where Stainless Steel 304 will get sensitized or where Stainless Steel304L lacks enough hot strength due to its resistance to sensitization and increased strength at high temperatures.
