Why Choose Stainless Steel 321 Lap Joint Flanges?

Stainless Steel 321 is a preferred material for flanges because it combines durability with high-temperature performance. The alloy includes titanium, which stabilizes it and prevents chromium carbide formation. This feature is crucial in avoiding intergranular corrosion. Therefore, SS 321 is ideal for use in environments with fluctuating temperatures.

  • Corrosion Resistance: SS 321 provides excellent resistance to corrosion from various acids, alkalis, and chlorides. This makes it versatile for numerous applications.
  • High-Temperature Strength: The alloy retains its mechanical properties at temperatures up to 800°C (1472°F). This ensures consistent performance in high-heat environments.
  • Ease of Fabrication: SS 321 is easy to weld and fabricate. It allows for the construction of complex systems without the risk of sensitization, a concern in other stainless steels.
