Key Features of Type 321 Stainless Steel

1. Titanium Stabilization:

   • Titanium is added to prevent carbide precipitation during welding or high-temperature exposure, reducing the risk of intergranular corrosion.

2. High-Temperature Resistance:

   • Excellent resistance to scaling and oxidation in continuous service up to 900°C (1650°F).
   • Superior creep and stress rupture properties compared to Type 304.

3. Good Corrosion Resistance:

   • Performs well in moderately corrosive environments, particularly in oxidizing conditions.

4. Weldability and Formability:

   • Excellent weldability with minimal risk of sensitization.
   • Can be easily formed into complex shapes.

5. Non-Magnetic:

   • Retains non-magnetic properties in annealed conditions.
