Stainless Steel 321 Flanges deliver titanium-stabilized corrosion resistance with excellent weldability for high-temperature applications at Salem Stainless Steel Suppliers Pvt. Ltd. This enhanced 304 variant prevents carbide precipitation during welding, ensuring long-term integrity in heat-exposed piping systems.
As a titanium-stabilized austenitic stainless steel, Grade 321 is specifically designed to perform in the “sensitization” temperature range (427°C to 815°C). The defining characteristic of SS 321 Flanges is the addition of Titanium. Titanium has a stronger affinity for carbon than chromium does; it forms titanium carbides that stay dispersed throughout the metal, ensuring the chromium remains available to provide its signature corrosion protection.
